00:00:46,480 --> 00:00:50,000 ...It has its origin billions of years ago. 5 00:00:53,320 --> 00:00:57,160 small single celled organisms started a journey... 6 00:00:57,520 --> 00:01:03,480 ...with an amazing engine, natural selection. 7 00:01:04,440 --> 00:01:06,760 It all started in the sea. 8 00:01:06,880 --> 00:01:08,360 In this salty environment... 9 00:01:08,480 --> 00:01:11,560 ...these little beings were adapting and grouping... 10 00:01:11,680 --> 00:01:15,600 ...until they form more complex organisms. 11 00:01:15,720 --> 00:01:19,680 ...and thus, be the basis of all life on the planet. 12 00:01:25,040 --> 00:01:28,760 Paradoxically, the evolution has led to the environment... 13 00:01:28,880 --> 00:01:32,280 ...where those little beings they started it all... 14 00:01:32,560 --> 00:01:34,920 ...today live the biggest animals... 15 00:01:35,040 --> 00:01:37,800 ...they never have existed on earth... 16 00:01:37,920 --> 00:01:39,280 ...the whales. 17 00:01:54,240 --> 00:01:57,600 The Cantabrian Sea It is home to many cetaceans... 18 00:01:57,880 --> 00:02:00,760 ...among them the fin whale. 19 00:02:00,920 --> 00:02:04,160 It is the second largest animal that exists on the planet. 20 00:02:04,720 --> 00:02:08,000 can reach 27 meters long... 21 00:02:08,120 --> 00:02:11,880 ...and weigh up to 90 tons. 22 00:02:12,000 --> 00:02:14,760 a real giant from the depths of the sea. 23 00:02:18,560 --> 00:02:20,040 It's not the only one. 24 00:02:20,320 --> 00:02:25,160 common dolphins, listings, mules and pilot whales... 25 00:02:25,280 --> 00:02:29,080 They all swim in the waters of the Cantabrian Sea. 26 00:02:36,640 --> 00:02:39,560 They are mammals that live in social groups... 27 00:02:39,680 --> 00:02:41,480 ...and this gives them increased protection. 28 00:02:42,080 --> 00:02:46,400 The larger the group, stronger they are. 29 00:02:54,440 --> 00:02:58,840 Common and striped dolphins they swim in a prodigious way... 30 00:02:58,960 --> 00:03:01,360 ...and they are, the great acrobats of the sea. 31 00:03:28,560 --> 00:03:32,520 They communicate with each other by a complex system of sounds... 32 00:03:32,640 --> 00:03:36,760 ...which also works for them to echolocate their prey. 33 00:03:41,960 --> 00:03:46,000 Thanks to evolutionary processes They have conquered the sea... 34 00:03:46,120 --> 00:03:48,680 ...and today they show his impressive abilities... 35 00:03:48,800 --> 00:03:52,640 ...to live in this hostile environment. 36 00:04:11,240 --> 00:04:12,520 But sometimes... 37 00:04:12,640 --> 00:04:15,360 ...life comes to an end much sooner than expected. 38 00:04:18,280 --> 00:04:22,160 It's a freshly killed baby Cuvier's calf. 39 00:04:23,600 --> 00:04:26,400 his lifeless body floating in the middle of the sea... 40 00:04:26,680 --> 00:04:29,240 ...in the adjacent waters to the Cap Breton canyon. 41 00:04:31,680 --> 00:04:34,920 They live in waters of more 1000 meters deep. 42 00:04:38,720 --> 00:04:40,320 Not alone. 43 00:04:40,800 --> 00:04:42,560 Her mother approaches. 44 00:04:47,240 --> 00:04:50,000 this is a moment never before filmed: 45 00:04:51,600 --> 00:04:56,640 ...the mourning of a mother from Cuvier's beaked whale to her calf. 46 00:05:07,120 --> 00:05:09,360 This baby may have died... 47 00:05:09,480 --> 00:05:11,680 ...for having risen to the surface too fast... 48 00:05:11,800 --> 00:05:15,640 ...provoking this fatal multi-organ failure. 49 00:05:28,680 --> 00:05:31,120 She is reluctant to leave her. 50 00:05:31,520 --> 00:05:34,760 He tries to revive her and again... 51 00:05:36,320 --> 00:05:37,960 ...But it's in vain. 52 00:06:25,120 --> 00:06:26,120 Finally... 53 00:06:26,240 --> 00:06:31,400 ...after a long time, he says goodbye to her. 54 00:06:45,680 --> 00:06:48,080 on the seabed near the coast... 55 00:06:48,480 --> 00:06:50,360 ...we find extensive meadows of algae 56 00:06:53,680 --> 00:06:57,040 They are the ideal home for many species. 57 00:06:57,160 --> 00:07:02,080 Some seek protection here and go unnoticed. 58 00:07:06,480 --> 00:07:09,600 Although they are changing marine habitats... 59 00:07:09,760 --> 00:07:12,160 ...for the increase temperature of the oceans... 60 00:07:12,280 --> 00:07:16,160 ...there are still beautiful corners with abundant marine life. 61 00:07:29,080 --> 00:07:30,560 In large areas of sand... 62 00:07:30,680 --> 00:07:34,120 ...at first sight there doesn't seem to be anything... 63 00:07:39,120 --> 00:07:41,760 ...but a seashell It is the ideal home... 64 00:07:41,880 --> 00:07:43,920 ...for a male sand goby. 65 00:07:49,040 --> 00:07:53,120 Between so much sand it is not easy find shelter... 66 00:07:53,240 --> 00:07:54,320 ...so that... 67 00:07:54,440 --> 00:07:56,760 ...you have to defend it against other potential adversaries. 68 00:08:01,240 --> 00:08:02,920 It only has one goal: 69 00:08:03,360 --> 00:08:07,080 ...let the female through that she decides to deposit her eggs... 70 00:08:07,200 --> 00:08:09,000 ...inside the shell. 71 00:08:13,120 --> 00:08:15,800 Something catches his attention. 72 00:08:15,920 --> 00:08:19,880 He comes out of his shell to take a closer look. 73 00:08:20,600 --> 00:08:21,880 Are they leeches? 74 00:08:24,760 --> 00:08:27,760 Up close he didn't owe her looking interesting... 75 00:08:27,960 --> 00:08:29,760 ... and he decides to leave, ... 76 00:08:30,160 --> 00:08:32,240 ...but he doesn't go as fast as ever... 77 00:08:32,360 --> 00:08:36,080 ...perhaps still hold some curiosity. 78 00:08:40,880 --> 00:08:44,200 the sea can be full of surprises. 79 00:08:48,480 --> 00:08:51,560 The shaking ray returns to hide under the sand... 80 00:08:51,680 --> 00:08:53,480 ...and will wait hidden... 81 00:08:53,600 --> 00:08:56,920 ...gives that a clueless fish walk by her again. 82 00:09:09,320 --> 00:09:10,720 If we look up... 83 00:09:10,840 --> 00:09:14,160 ...we can observe others interesting traveling companions... 84 00:09:15,400 --> 00:09:17,080 ...seabirds. 85 00:09:18,920 --> 00:09:23,440 They are magnificent bioindicators of the state of health of the sea... 86 00:09:23,880 --> 00:09:25,960 ...that are approaching to groups of cetaceans... 87 00:09:26,080 --> 00:09:28,760 ...when it appears some school of fish. 88 00:09:29,240 --> 00:09:32,080 Gannets, seagulls, pair of... 89 00:09:32,600 --> 00:09:33,640 Many of them... 90 00:09:33,760 --> 00:09:38,080 ...the coldest months of the year pass in the Cantabrian Sea. 91 00:10:06,400 --> 00:10:09,480 weather conditions They are adverse during the winter... 92 00:10:09,640 --> 00:10:13,760 ...and northwesterly winds they hit hard. 93 00:10:18,000 --> 00:10:19,480 In full storm... 94 00:10:19,600 --> 00:10:22,800 ...the swell can overcome ten meters high. 95 00:10:27,400 --> 00:10:28,440 Nevertheless... 96 00:10:28,560 --> 00:10:32,440 ...this is a very special time for the shag. 97 00:10:35,400 --> 00:10:38,120 a bird that breeds on the sea cliffs... 98 00:10:38,240 --> 00:10:40,960 ...and that she is used to to inclement weather. 99 00:10:45,400 --> 00:10:48,120 Slowly, the coast is full of birds. 100 00:10:52,040 --> 00:10:54,640 and you can see them forming small colonies. 101 00:10:58,160 --> 00:11:01,200 they are impatient to take advantage of the breeding season... 102 00:11:04,200 --> 00:11:05,600 ...and it's now... 103 00:11:05,720 --> 00:11:09,880 ...when the shag, lives up to his name... 104 00:11:10,280 --> 00:11:11,600 ...and the only time of the whole year... 105 00:11:11,720 --> 00:11:15,240 ...in which it shines their nuptial plumage... 106 00:11:15,400 --> 00:11:18,800 ...and when in his silhouette highlights a prominent bun. 107 00:11:19,720 --> 00:11:23,600 This makes them more attractive for their respective partners. 108 00:11:28,600 --> 00:11:30,720 Temperatures have dropped a lot. 109 00:11:33,200 --> 00:11:38,000 It's February and winter in puts its conditions. 110 00:11:38,760 --> 00:11:41,480 this past morning It has snowed at sea level. 111 00:11:44,840 --> 00:11:47,440 It is very likely that this male peregrine falcon... 112 00:11:47,560 --> 00:11:50,600 ...is watching the snow for the first time in his life. 113 00:11:53,640 --> 00:11:55,640 This will be your nest... 114 00:11:55,840 --> 00:11:58,440 ...A plataform from a rocky cliff... 115 00:11:58,560 --> 00:11:59,720 ...of the Basque coast. 116 00:12:04,360 --> 00:12:05,880 In a few hours... 117 00:12:06,000 --> 00:12:09,880 ...it starts to rain and the snow recedes. 118 00:12:14,040 --> 00:12:15,840 The female arrives at the nest... 119 00:12:16,200 --> 00:12:18,480 ...and it seems that all the work... 120 00:12:18,600 --> 00:12:21,000 ...done the days before it has disappeared. 121 00:12:27,680 --> 00:12:30,120 It is three to day because of what has happened... 122 00:12:30,240 --> 00:12:33,160 ...he strives to return to shape the bucket... 123 00:12:38,800 --> 00:12:40,560 ...but it's not a good time... 124 00:12:40,680 --> 00:12:44,000 ...Better wait for the snow disappear completely. 125 00:12:54,000 --> 00:12:55,280 In the meantime... 126 00:12:55,560 --> 00:12:59,680 ...the shags They continue with their processions. 127 00:13:06,000 --> 00:13:07,480 Unless there are casualties... 128 00:13:07,600 --> 00:13:10,840 ...couples remain stable, year after year. 129 00:13:22,200 --> 00:13:24,840 During the rest of the year They split up to search... 130 00:13:24,960 --> 00:13:27,040 ...the best food areas... 131 00:13:27,160 --> 00:13:30,640 ...but they always come back to the same place to breed. 132 00:13:31,240 --> 00:13:33,920 They can pass long months without seeing each other... 133 00:13:34,040 --> 00:13:36,320 ...Thus, when they get back together... 134 00:13:36,440 --> 00:13:39,320 ...they have to tighten again the links. 135 00:13:43,480 --> 00:13:45,760 This year they are late... 136 00:13:45,880 --> 00:13:47,880 ...so they'll have to hurry... 137 00:13:48,000 --> 00:13:49,440 ...and dedicate the following days... 138 00:13:49,560 --> 00:13:52,920 ...in collecting the best material to rebuild their nest. 139 00:13:55,480 --> 00:13:57,080 Seems like a simple task... 140 00:13:57,640 --> 00:14:00,800 ...but raises its difficulties to the shags. 141 00:14:03,200 --> 00:14:05,000 They spend about two weeks... 142 00:14:05,120 --> 00:14:08,520 ...da search meticulously each of the branches they need. 143 00:14:11,520 --> 00:14:15,560 not easy to find the ones that best adapt to the nest... 144 00:14:16,000 --> 00:14:19,800 ...and sometimes they become very picky with your choice. 145 00:14:24,000 --> 00:14:27,320 And when it seems that until the same branch chooses them... 146 00:14:29,200 --> 00:14:32,680 ...it also doesn't turn out to be The most appropriate. 147 00:14:47,640 --> 00:14:52,680 Not all coastal communities They have the same times. 148 00:14:53,440 --> 00:14:56,520 on this cliff there are several nests... 149 00:14:56,640 --> 00:14:59,520 ...and some of them They are more advanced than others. 150 00:15:05,040 --> 00:15:07,320 Small or big,... 151 00:15:07,600 --> 00:15:09,360 ...everyone is anxiously waiting... 152 00:15:09,480 --> 00:15:12,000 ...upon the arrival of their parents for them to feed. 153 00:15:19,080 --> 00:15:20,880 The insistence of the pups... 154 00:15:21,000 --> 00:15:24,040 ...sometimes you can even be overwhelming. 155 00:15:29,240 --> 00:15:31,800 From the distance It looks kind of violent... 156 00:15:31,920 --> 00:15:33,920 ...But it's the way what about chickens... 157 00:15:34,040 --> 00:15:35,560 ...of regurgitating food... 158 00:15:35,680 --> 00:15:37,640 ...their parents and thus be able to feed. 159 00:15:43,360 --> 00:15:46,160 In this other nest, we only found a chicken... 160 00:15:46,960 --> 00:15:49,840 ...but there wasn't plenty of room for more. 161 00:15:54,200 --> 00:15:58,080 With its small size, They have to adapt as they can... 162 00:15:58,360 --> 00:16:02,480 ...because any movement in such can be fatal. 163 00:16:15,960 --> 00:16:20,400 But on the coast not everything is sea water. 164 00:16:21,080 --> 00:16:23,800 There are environments where the fresh waters of the rivers... 165 00:16:23,920 --> 00:16:26,760 ...merge with the salty waters coming from the sea... 166 00:16:26,880 --> 00:16:28,800 ...giving rise to estuaries. 167 00:16:38,040 --> 00:16:41,120 It is in this union between land and sea... 168 00:16:41,240 --> 00:16:44,240 ...where they can be found Truly unique species. 169 00:16:48,840 --> 00:16:50,760 They stand out for their ecological richness... 170 00:16:50,880 --> 00:16:56,960 ...that of Urdaibai in Vizcaya and Txingudi in Guipúzcoa. 171 00:17:02,640 --> 00:17:06,640 They are fertile areas and rich in food... 172 00:17:07,080 --> 00:17:08,600 ...which serve as supplies... 173 00:17:08,720 --> 00:17:11,120 ...to many species of our avitauna... 174 00:17:11,240 --> 00:17:12,840 ...which are forced to travel... 175 00:17:12,960 --> 00:17:15,160 ...very long distances flying over the sea. 176 00:17:24,200 --> 00:17:26,840 And the hawks know it. 177 00:17:27,320 --> 00:17:29,600 They choose the coast to live... 178 00:17:29,720 --> 00:17:32,280 ...because of the large quantity of food there is. 179 00:17:35,440 --> 00:17:38,200 the female falcon She has laid four eggs. 180 00:17:39,680 --> 00:17:41,760 They will hatch in a few days. 181 00:17:43,920 --> 00:17:46,200 It is the most delicate moment. 182 00:17:46,520 --> 00:17:50,200 temperatures have dropped and the rain does not stop. 183 00:17:52,600 --> 00:17:55,080 The nest is too exposed... 184 00:17:55,200 --> 00:17:58,120 ...and the mother has been holding on underwater three days. 185 00:17:59,600 --> 00:18:03,640 With so much humidity she can become weak and sick. 186 00:18:04,360 --> 00:18:08,280 He can replace her but for a short time. 187 00:18:08,680 --> 00:18:12,400 it is much smaller and he can't incubate the eggs well. 188 00:18:13,200 --> 00:18:16,360 The female will have to return as soon as possible... 189 00:18:16,480 --> 00:18:18,640 ... so as not to lose her start. 190 00:18:23,080 --> 00:18:27,200 Of the four eggs that she laid only one was born 191 00:18:28,160 --> 00:18:29,240 Climate change is... 192 00:18:29,360 --> 00:18:32,280 ...the main threat of the peregrine falcon. 193 00:18:34,400 --> 00:18:36,920 the incessant rain and low temperatures... 194 00:18:37,320 --> 00:18:38,440 ...at the time of hatching... 195 00:18:38,560 --> 00:18:40,720 ...man made three chickens they will not be born. 196 00:18:42,880 --> 00:18:44,800 This is a determining factor... 197 00:18:44,920 --> 00:18:47,560 ...during the breeding season of many birds. 198 00:18:51,240 --> 00:18:53,440 the hawk chick he is hungry... 199 00:18:53,880 --> 00:18:55,840 ...he hasn't eaten for several hours... 200 00:18:56,280 --> 00:18:59,080 ...And the father does not return with food. 201 00:19:01,560 --> 00:19:05,920 The mother can't leave him alone because you could be in danger. 202 00:19:07,400 --> 00:19:08,600 They have to wait... 203 00:19:08,720 --> 00:19:12,000 ...gives that the peregrine male come back with some food. 204 00:19:22,520 --> 00:19:25,280 falcon's father detect motion... 205 00:19:25,600 --> 00:19:28,360 ...and he Pounces on his prey. 206 00:19:31,000 --> 00:19:33,000 It is the fastest animal in the world... 207 00:19:33,120 --> 00:19:37,800 ...and will swoop down the 300 km/h. 208 00:19:39,680 --> 00:19:41,640 This maximizes the chances of him... 209 00:19:41,760 --> 00:19:44,520 ...to capture to agile prey in the air. 210 00:19:53,840 --> 00:19:55,960 But before going to the nest... 211 00:19:56,360 --> 00:19:58,880 ...will have to stop to pluck the prey well... 212 00:19:59,280 --> 00:20:01,120 ...besides eating him too. 213 00:20:12,400 --> 00:20:15,400 he can come back and feed your little one. 214 00:20:18,320 --> 00:20:20,160 After the long wait... 215 00:20:20,280 --> 00:20:24,400 ...the family of pilgrims welcomes the return of the father with enthusiasm. 216 00:20:27,760 --> 00:20:30,880 Weather conditions of the last few years... 217 00:20:31,000 --> 00:20:34,200 ...they are complicating the season a lot reproduction of this species. 218 00:20:36,240 --> 00:20:41,040 the heavy rains and the cold at key moments... 219 00:20:41,160 --> 00:20:43,920 ...make many adults get sick and die. 220 00:20:44,040 --> 00:20:45,200 At other times... 221 00:20:45,320 --> 00:20:49,520 ...it is the chickens who suffer and die in the nest. 222 00:20:49,800 --> 00:20:53,560 This couple had been four years without being able to breed successfully... 223 00:20:53,760 --> 00:20:55,960 ...for what they will have to do everything possible... 224 00:20:56,080 --> 00:20:58,400 ...to get ahead to his only son. 225 00:21:11,480 --> 00:21:14,040 in the countless geometric forms... 226 00:21:14,160 --> 00:21:17,960 ...and towering cliffs that make up the Basque coastline... 227 00:21:18,440 --> 00:21:22,360 ...we find various jewels geology of incalculable value. 228 00:21:29,720 --> 00:21:32,720 The water and the wind They erode these rocks... 229 00:21:32,840 --> 00:21:35,320 ...Forming a unique landscape. 230 00:21:38,880 --> 00:21:40,720 Some of them... 231 00:21:40,840 --> 00:21:45,160 ...like those of Jaizkibel, They go beyond beauty. 232 00:21:55,440 --> 00:21:58,160 The high concentration of these geoforms... 233 00:21:58,280 --> 00:22:02,560 ...so particular and colorful They are more than 40 million years old. 234 00:22:08,640 --> 00:22:12,280 This impressive diversity shapes, sizes and colors... 235 00:22:12,400 --> 00:22:15,000 ...is one of the best examples sculptured sandstone... 236 00:22:15,200 --> 00:22:18,960 ...by nature known worldwide. 237 00:22:22,160 --> 00:22:23,200 The sea... 238 00:22:23,320 --> 00:22:26,720 ...indifferent to treasures geology of the cliffs... 239 00:22:26,840 --> 00:22:29,240 ...with its waves, tide after tide... 240 00:22:29,640 --> 00:22:33,280 ...snatches small fragments from them of that story. 241 00:22:37,320 --> 00:22:40,920 Because of that perpetual struggle from the sea to the land... 242 00:22:41,040 --> 00:22:44,960 ...it forms an ecosystem of great value... 243 00:22:45,080 --> 00:22:47,040 ...the intertidal flat... 244 00:22:47,160 --> 00:22:51,000 ...very rich in species of marine fauna and flora. 245 00:22:51,560 --> 00:22:54,840 The two most prominent we found them in Ogella... 246 00:22:54,960 --> 00:22:56,920 ...and in the impressive rock strata... 247 00:22:57,040 --> 00:23:00,440 ...of the Geopark Flysch from the Basque coast. 248 00:23:01,680 --> 00:23:03,160 This rocky platform... 249 00:23:03,280 --> 00:23:06,680 ...that emerges at the feet of the cliffs of Deba and Zumaia... 250 00:23:06,840 --> 00:23:11,360 ...is the greatest book ever written on the face of the earth. 251 00:23:14,080 --> 00:23:15,840 And the scientists... 252 00:23:15,960 --> 00:23:18,640 ...you can read in these layers, page by page... 253 00:23:18,760 --> 00:23:23,480 ...more than 50 million years of the history of our planet. 254 00:23:35,160 --> 00:23:36,680 When the tide goes out... 255 00:23:37,080 --> 00:23:40,080 ...the pools become in real aquariums. 256 00:23:42,120 --> 00:23:44,800 But it's not easy living here... 257 00:23:45,280 --> 00:23:46,600 ...during hot days... 258 00:23:46,720 --> 00:23:50,640 ...temperature and salinity of these waters are very high... 259 00:23:50,880 --> 00:23:53,760 ...and the organisms that inhabit them. 260 00:23:53,880 --> 00:23:56,600 ...have to endure these harsh conditions... 261 00:23:56,720 --> 00:23:59,040 ...until the tide comes in again. 262 00:24:06,240 --> 00:24:09,040 One of the most curious animals What do we find here... 263 00:24:09,160 --> 00:24:10,720 ...is the nudibranch. 264 00:24:13,240 --> 00:24:16,240 About 3000 species are known other than nudibranchs... 265 00:24:16,440 --> 00:24:20,560 ...and More than 100 They live in the Cantabrian Sea. 266 00:24:22,080 --> 00:24:23,360 Brightly colored... 267 00:24:23,480 --> 00:24:27,520 ...whimsical shapes and unimaginable designs. 268 00:24:29,240 --> 00:24:31,440 The variety is endless. 269 00:24:32,960 --> 00:24:35,800 But don't be fooled. 270 00:24:36,320 --> 00:24:39,800 These beautiful colors are One of the strategies they have... 271 00:24:40,320 --> 00:24:43,840 ...to warn predators of its toxicity. 272 00:24:46,520 --> 00:24:50,760 Sponges, anemones or hydrozoans They are part of their diet. 273 00:24:50,880 --> 00:24:54,320 ...the place they choose to live. 274 00:25:00,120 --> 00:25:01,840 Meetings are usually rare... 275 00:25:01,960 --> 00:25:05,560 ...because its small size It does not allow them to move much. 276 00:25:09,240 --> 00:25:12,840 When they meet an individual of the same kind... 277 00:25:12,960 --> 00:25:16,000 ...can't lose the opportunity to mate. 278 00:25:17,120 --> 00:25:19,000 They are hermaphrodites... 279 00:25:19,120 --> 00:25:21,040 ...possess both sexual organs 280 00:25:21,160 --> 00:25:24,960 ...to get the most out of it to this meeting. 281 00:25:37,000 --> 00:25:38,320 Curiously... 282 00:25:38,760 --> 00:25:42,760 ...far from the sea, it is possible find trace of marine life... 283 00:25:43,160 --> 00:25:45,320 ...a Although in this case petrified,.. 284 00:25:45,960 --> 00:25:48,640 ...because a good part from the Basque limestone mountains... 285 00:25:48,760 --> 00:25:51,440 ...contain fossils from various organizations... 286 00:25:51,760 --> 00:25:53,760 ...what are you doing over 100 million years... 287 00:25:53,880 --> 00:25:57,640 ...lived in shallow seas. 288 00:26:14,000 --> 00:26:19,240 These limestone mountains form landscapes of incredible beauty... 289 00:26:22,320 --> 00:26:28,640 ...Urkiola, Gorbeia, Aizkorri-Aratz, Urbasa, Aralar... 290 00:26:35,240 --> 00:26:39,080 In some cases the water has managed to carve these rocks... 291 00:26:39,200 --> 00:26:42,240 ...giving place to wonderful karstic environments. 292 00:26:47,800 --> 00:26:51,960 And in others, they have risen large rock walls. 293 00:26:59,360 --> 00:27:04,960 They are the home of the wallcreeper, the butterfly of the mountains 294 00:27:07,840 --> 00:27:10,240 life in these walls inhospitable in appearance... 295 00:27:10,400 --> 00:27:12,600 ...it doesn't seem easy,... 296 00:27:12,720 --> 00:27:16,680 ...but this little bird is fully adapted to live here. 297 00:27:18,280 --> 00:27:22,560 His fingers are long and strong To be able to scale these walls... 298 00:27:24,840 --> 00:27:27,040 ...and its long, thin beak To catch... 299 00:27:27,160 --> 00:27:29,080 ...to small living beings... 300 00:27:29,200 --> 00:27:31,360 ...that are hiding in the cracks and holes. 301 00:27:35,240 --> 00:27:38,600 check carefully each of them... 302 00:27:40,000 --> 00:27:42,520 ...she doesn't want to leave anything behind. 303 00:27:45,000 --> 00:27:49,400 And when she finds a place with a potential hidden prey... 304 00:27:49,520 --> 00:27:52,360 ... he does not hesitate to try to find her. 305 00:27:58,600 --> 00:28:01,160 Although not all small invertebrates of these areas... 306 00:28:01,280 --> 00:28:03,080 ...they make it easy... 307 00:28:03,520 --> 00:28:05,600 ...some are very slippery... 308 00:28:05,720 --> 00:28:10,320 ...and put to the test the agility of the wallcreeper. 309 00:28:11,000 --> 00:28:12,520 But usually... 310 00:28:12,640 --> 00:28:16,240 ...your favorite food are the insects... 311 00:28:16,360 --> 00:28:18,960 ...and other little animals they don't fly 312 00:28:22,520 --> 00:28:26,520 It is known as butterfly of the mountains... 313 00:28:26,640 --> 00:28:29,600 ...by how it spreads its wings and by your type of flight. 314 00:28:36,360 --> 00:28:39,440 He is quite an acrobat of the most vertical walls. 315 00:28:39,920 --> 00:28:45,040 Even so, It's not all as pretty as it seems. 316 00:28:47,920 --> 00:28:48,840 This male... 317 00:28:48,960 --> 00:28:51,640 ...as well as most of individuals of their species... 318 00:28:51,760 --> 00:28:54,920 ...It has had to be moved from their breeding grounds. 319 00:28:56,720 --> 00:28:57,800 In the winter... 320 00:28:57,920 --> 00:29:02,200 ...has to move to higher altitudes lower to feed... 321 00:29:02,440 --> 00:29:05,760 ...because the high peaks in which he breeds... 322 00:29:05,880 --> 00:29:08,000 ...are covered in snow and access to food... 323 00:29:08,120 --> 00:29:10,360 ...becomes in an almost impossible task. 324 00:29:16,480 --> 00:29:20,440 We now move to those high peaks of the Navarrese Pyrenees. 325 00:29:24,680 --> 00:29:27,720 a white cloak covers the landscape... 326 00:29:29,960 --> 00:29:33,480 ...and more snow is coming from the west. 327 00:29:39,560 --> 00:29:48,040 The strong gusty blizzard ravages the peaks of the Larra massif. 328 00:29:51,480 --> 00:29:52,520 Wind... 329 00:29:52,640 --> 00:29:59,040 ...low temperatures and snow They make it difficult to live here. 330 00:30:04,040 --> 00:30:05,240 Nevertheless... 331 00:30:05,360 --> 00:30:09,000 ...although the harsh winter in such harsh conditions... 332 00:30:09,120 --> 00:30:11,680 ...there are animals who challenge and adapt... 333 00:30:11,800 --> 00:30:14,280 ...prodigiously to this inhospitable environment. 334 00:30:20,080 --> 00:30:24,000 A group of chamois resists hard these harsh conditions. 335 00:30:28,840 --> 00:30:31,960 The snowfall has covered its entire territory... 336 00:30:32,280 --> 00:30:35,320 ...so they have to search food on the rocky walls... 337 00:30:35,520 --> 00:30:38,360 ...where the accumulation of snow is minor. 338 00:30:44,560 --> 00:30:45,960 To access them... 339 00:30:46,080 --> 00:30:48,320 ...have to save a steep slope... 340 00:30:48,440 --> 00:30:51,160 ...and cross a section with a lot of snow. 341 00:30:51,760 --> 00:30:54,160 When the precipitation they are copious... 342 00:30:54,280 --> 00:30:57,880 ...the accumulated snow reaches two meters thick... 343 00:30:58,000 --> 00:31:00,080 ...and the specimens with more experience... 344 00:31:00,200 --> 00:31:01,160 ...they are opening the way... 345 00:31:01,280 --> 00:31:04,000 ...to reach to feeding areas. 346 00:31:06,920 --> 00:31:09,400 Once they have arrived at the base of the cut... 347 00:31:09,520 --> 00:31:12,440 ...they have no choice to climb on it... 348 00:31:12,560 --> 00:31:15,560 ...and gain height to access to the best feeding areas. 349 00:31:17,120 --> 00:31:19,360 This requires great skill... 350 00:31:19,480 --> 00:31:23,920 ...but the sarrio is fully prepared for it. 351 00:31:25,600 --> 00:31:29,520 His hooves are perfectly adapted for jumping and running... 352 00:31:29,640 --> 00:31:32,600 ...without falling for these steep mountain slopes. 353 00:31:36,840 --> 00:31:37,960 And the youngest... 354 00:31:38,080 --> 00:31:41,160 ...practice these skills in an extraordinary way. 355 00:31:51,720 --> 00:31:53,680 the extreme conditions meteorological... 356 00:31:53,800 --> 00:31:58,440 ...put every winter these animals to the test... 357 00:31:58,560 --> 00:32:01,720 ...so that alone, the best adapted survive. 358 00:32:02,400 --> 00:32:05,720 It's a fight between life and death. 359 00:32:24,280 --> 00:32:27,040 Flying over the peaks of the Navarrese Pyrenees... 360 00:32:27,160 --> 00:32:29,520 ...we observed the bearded vulture. 361 00:32:33,280 --> 00:32:36,320 With its almost three meters large... 362 00:32:36,440 --> 00:32:38,480 ...this legendary bird from the mountains... 363 00:32:38,600 --> 00:32:42,640 ...glides over the snow blanket in search of food. 364 00:32:45,120 --> 00:32:48,000 Any leftover carrion It will be enough... 365 00:32:48,120 --> 00:32:50,720 ...to sustain her during several days. 366 00:32:53,000 --> 00:32:55,200 a group of vultures draw your attention... 367 00:32:55,320 --> 00:32:57,160 ...and decides to go down with them. 368 00:32:59,920 --> 00:33:04,680 A carrion from yesterday has been covered because of the recent snowfall... 369 00:33:04,800 --> 00:33:06,800 ...and your search It becomes a competition... 370 00:33:06,920 --> 00:33:09,880 ...between different species to find the best remains. 371 00:33:12,520 --> 00:33:15,840 There are more bearded vultures in the area. 372 00:33:16,960 --> 00:33:20,120 In the winter And in the face of food shortages... 373 00:33:20,240 --> 00:33:23,040 ...a carrion becomes a claim... 374 00:33:23,160 --> 00:33:25,800 ...for individuals from other territories. 375 00:33:31,440 --> 00:33:33,120 Although the ghouls... 376 00:33:33,240 --> 00:33:35,720 ...like vultures and the bearded vultures... 377 00:33:35,840 --> 00:33:38,680 ...don't be predators, at times like this... 378 00:33:38,800 --> 00:33:41,200 ...there are no cordialities. 379 00:33:43,600 --> 00:33:46,120 there is not enough food for all... 380 00:33:46,240 --> 00:33:49,160 ...so, they will have to fight for it. 381 00:34:08,920 --> 00:34:13,280 The bearded vulture searches between the snow the bones... 382 00:34:13,400 --> 00:34:15,600 ...they are the only thing that interests him. 383 00:34:16,160 --> 00:34:17,760 When he finds one if he is small... 384 00:34:17,880 --> 00:34:19,960 ...devours it with ease. 385 00:34:25,760 --> 00:34:28,160 The ravens are in the area. 386 00:34:28,400 --> 00:34:31,000 Despite not competing for the same food... 387 00:34:31,120 --> 00:34:34,200 ...follow the footsteps closely of bearded vultures. 388 00:34:39,920 --> 00:34:43,640 your insistence to get some food... 389 00:34:43,760 --> 00:34:46,280 ...becomes irritating to the big birds. 390 00:34:57,880 --> 00:35:00,640 During this time begins the zeal of the bearded vulture... 391 00:35:00,760 --> 00:35:04,120 ...and couples fly together and in sync... 392 00:35:04,240 --> 00:35:06,120 ...to strengthen their union... 393 00:35:06,240 --> 00:35:08,560 ...before putting on to prepare the nest. 394 00:35:16,560 --> 00:35:20,600 With the cessation of rain and snow Spring arrives. 395 00:35:23,240 --> 00:35:26,800 The high peaks become the restart of life. 396 00:35:30,960 --> 00:35:32,960 The water gushes out... 397 00:35:33,360 --> 00:35:36,720 ...and rushes down the steep slopes. 398 00:35:46,160 --> 00:35:49,480 The meadows prepare to bloom 399 00:35:54,040 --> 00:35:55,240 And some residents... 400 00:35:55,360 --> 00:35:57,760 ...who have spent the winter refugees underground... 401 00:35:57,880 --> 00:35:59,840 ...wake up from torpor... 402 00:36:00,200 --> 00:36:03,480 ...to feel on your face the soft spring wind. 403 00:36:08,800 --> 00:36:10,680 The little marmots... 404 00:36:10,800 --> 00:36:13,480 ...come to the surface in order to feed... 405 00:36:13,600 --> 00:36:15,560 ...of the first flowers and fresh grass... 406 00:36:15,680 --> 00:36:17,920 ...that fill the mountain slopes. 407 00:36:23,240 --> 00:36:26,080 The little ones are entertained playing with each other... 408 00:36:26,200 --> 00:36:29,720 ...while the older sunbathe 409 00:36:33,840 --> 00:36:38,320 But spend so much time grazing can have its dangers. 410 00:36:38,520 --> 00:36:41,800 These rodents are prey of many predators... 411 00:36:41,920 --> 00:36:42,960 ...so that... 412 00:36:43,080 --> 00:36:47,040 ...have to act fast when they detect any danger. 413 00:36:47,480 --> 00:36:49,320 As soon as the alarm sounds... 414 00:36:49,680 --> 00:36:51,480 ...they all disappear in a matter of seconds. 415 00:37:01,600 --> 00:37:03,280 in wooded areas another animal lives... 416 00:37:03,400 --> 00:37:07,000 ...that the long winter has passed asleep in his lair. 417 00:37:08,360 --> 00:37:10,200 It is the brown bear. 418 00:37:12,320 --> 00:37:13,880 A kind... 419 00:37:14,000 --> 00:37:18,160 ...that stopped inhabiting the forests del Roncal when Camille died... 420 00:37:18,800 --> 00:37:23,120 ...the last autochthonous specimen that He lived in the Pyrenees mountain range. 421 00:37:24,400 --> 00:37:26,160 Several years later... 422 00:37:26,520 --> 00:37:28,480 ...and thanks to the various reintroductions... 423 00:37:28,600 --> 00:37:30,920 ...that have been carried out in the French Pyrenees... 424 00:37:31,280 --> 00:37:32,680 ...this magnificent animal... 425 00:37:32,800 --> 00:37:35,160 ...inhabit again the Roncal forests. 426 00:37:40,760 --> 00:37:44,040 This bear has come out of her lethargy very hungry... 427 00:37:44,840 --> 00:37:48,280 ...and she is not alone, two little cubs go with her. 428 00:37:52,320 --> 00:37:54,680 Away from any danger... 429 00:37:54,800 --> 00:37:57,920 ...the little ones play and they fight each other. 430 00:37:58,320 --> 00:38:00,840 They taste good that their mother protects them. 431 00:38:01,640 --> 00:38:05,040 But she doesn't let her guard down. 432 00:38:10,800 --> 00:38:14,040 Suddenly the wind brings you bad news... 433 00:38:14,520 --> 00:38:17,480 ...not too far, has detected a male. 434 00:38:20,760 --> 00:38:24,160 The female has to avoid the encounter. 435 00:38:24,920 --> 00:38:28,640 If the male discovers them, the cubs could be in danger. 436 00:38:31,760 --> 00:38:34,080 The male is looking for a mate. 437 00:38:34,200 --> 00:38:36,880 But she is not receptive... 438 00:38:37,000 --> 00:38:40,480 ... and she has two kids and she will not go into heat ... 439 00:38:40,600 --> 00:38:43,080 ...until they have around one and a half years old... 440 00:38:43,200 --> 00:38:44,920 ...and become independent. 441 00:38:45,760 --> 00:38:50,160 So the bear you will have to continue your search. 442 00:38:56,680 --> 00:38:58,320 First thing in the morning... 443 00:38:58,440 --> 00:39:01,200 ...in these areas not very accessible... 444 00:39:01,320 --> 00:39:04,360 ...you can still hear the characteristic claim... 445 00:39:04,480 --> 00:39:07,000 ...of one of the most legendary birds from the mountain forests... 446 00:39:07,680 --> 00:39:09,520 ...the grouse. 447 00:39:13,960 --> 00:39:15,600 During the mating season... 448 00:39:15,720 --> 00:39:18,080 ...these impressive birds They gather in the singing areas... 449 00:39:18,520 --> 00:39:20,760 ...called cantaderos. 450 00:39:22,640 --> 00:39:25,400 This is where they shine. 451 00:39:51,320 --> 00:39:53,800 Today there is a female in the quarry. 452 00:39:54,960 --> 00:39:56,920 Something that is not very common here. 453 00:39:59,160 --> 00:40:03,880 The male knows it and continues to display all its charms... 454 00:40:04,000 --> 00:40:06,840 ...convinced that he will get the favor of the female. 455 00:40:08,640 --> 00:40:11,400 And he must have liked something... 456 00:40:15,440 --> 00:40:17,760 The male runs to where she is. 457 00:40:21,240 --> 00:40:23,520 And he walks over to stand next to her. 458 00:40:25,880 --> 00:40:28,520 But another male is watching him. 459 00:40:29,000 --> 00:40:31,360 he has also come to find a partner. 460 00:40:34,880 --> 00:40:37,200 He doesn't want to distance himself from her... 461 00:40:37,320 --> 00:40:40,400 ...because he knows that still he has not made any decision. 462 00:40:42,360 --> 00:40:45,160 Every male has his stage where to show off... 463 00:40:45,600 --> 00:40:48,600 ...and they control each other from a distance. 464 00:40:51,360 --> 00:40:53,760 But today they play a lot... 465 00:40:54,200 --> 00:40:56,680 ...and while the female take some distance... 466 00:40:56,800 --> 00:40:59,760 ...they will have to prove Who is the strongest. 467 00:41:01,320 --> 00:41:04,840 The fights between male capercaillies They are not usually fierce... 468 00:41:04,960 --> 00:41:07,200 ...but they are decisive. 469 00:41:07,720 --> 00:41:10,960 It remains to be decided whether any of them will continue this year... 470 00:41:11,080 --> 00:41:13,320 ...contributing to that the species continues to breed... 471 00:41:13,440 --> 00:41:16,000 ...in these forests of Roncal. 472 00:41:19,560 --> 00:41:23,240 At the moment, it seems that the female It doesn't decide for any... 473 00:41:23,360 --> 00:41:27,360 ...therefore, they will have to return to the quarry another day. 474 00:41:29,080 --> 00:41:32,920 Unfortunately, your situation is so critical... 475 00:41:33,160 --> 00:41:35,600 ...that maybe These three guys are... 476 00:41:35,720 --> 00:41:39,760 ...the last remaining grouse in the Larra Nature Reserve. 477 00:41:54,200 --> 00:41:56,920 It is here, in the pine forests... 478 00:41:57,320 --> 00:41:59,200 ...where hopefully... 479 00:41:59,480 --> 00:42:01,600 ...you can be a witness one of the events... 480 00:42:01,720 --> 00:42:03,880 ...more impressive of the nature. 481 00:42:08,600 --> 00:42:14,200 You have to look down at ground level and look closely. 482 00:42:16,600 --> 00:42:18,920 The needles move. 483 00:42:24,880 --> 00:42:27,200 Buried under the leaf litter... 484 00:42:27,640 --> 00:42:29,920 ...within a few centimeters Of the surface... 485 00:42:30,040 --> 00:42:32,960 ...a singular creature just emerged from its chrysalis. 486 00:42:41,320 --> 00:42:46,120 Fight to get out and break through from the forest floor... 487 00:42:47,040 --> 00:42:49,800 ...the same as until now It has been a protection... 488 00:42:49,920 --> 00:42:52,440 ...in front of winter and their predators. 489 00:43:04,760 --> 00:43:08,360 At last. It's already out. 490 00:43:13,280 --> 00:43:16,200 But this It was only the beginning... 491 00:43:16,520 --> 00:43:19,080 ...still has a long way to go in front. 492 00:43:21,960 --> 00:43:24,280 Athough it does not seems, he is in a hurry. 493 00:43:25,920 --> 00:43:28,800 need to find as soon as possible a tree to climb... 494 00:43:29,640 --> 00:43:32,880 ...otherwise you are in danger for their wings to dry. 495 00:43:33,720 --> 00:43:38,160 He has just the right time and is not entertained. 496 00:43:44,240 --> 00:43:46,520 as soon as you find a suitable place... 497 00:43:46,640 --> 00:43:49,440 ...It stops to finish his metamorphosis... 498 00:43:50,120 --> 00:43:53,320 ...one of the butterflies most beautiful in Europe... 499 00:43:53,600 --> 00:43:57,040 ...the Graellsia or Actias Isabelae. 500 00:43:58,680 --> 00:44:00,920 is one of the events most beautiful... 501 00:44:01,040 --> 00:44:02,600 ...that are produced In nature. 502 00:44:42,880 --> 00:44:46,600 Despite being a night butterfly, born during the day... 503 00:44:47,480 --> 00:44:51,280 ...because their wings need dry and stretch completely... 504 00:44:51,400 --> 00:44:53,440 ...before you can fly. 505 00:45:00,320 --> 00:45:02,560 The beauty of this butterfly... 506 00:45:02,680 --> 00:45:05,040 ...is more own of tropical species. 507 00:45:06,360 --> 00:45:08,440 Not in vain is it considered... 508 00:45:08,560 --> 00:45:11,160 ...as the most beautiful of European butterflies. 509 00:45:26,280 --> 00:45:28,160 When twilight comes... 510 00:45:28,320 --> 00:45:30,800 ...the graellsia or Elizabethan... 511 00:45:31,000 --> 00:45:35,200 ...starts to vibrate the wings to generate internal heat... 512 00:45:35,600 --> 00:45:38,840 ...necessary to take off and be able to take flight. 513 00:45:39,200 --> 00:45:42,640 Just in time to find a partner... 514 00:45:42,760 --> 00:45:44,320 ...In the darkness of the night. 515 00:46:00,960 --> 00:46:04,680 altitude, orientation and the type of soil help... 516 00:46:04,800 --> 00:46:08,840 ...since there is a great variety of forests in Euskadi and Navarra. 517 00:46:10,800 --> 00:46:13,320 These, in a vast majority... 518 00:46:13,440 --> 00:46:16,480 ...are populated by trees deciduous... 519 00:46:16,840 --> 00:46:20,160 ...Giving spectacular and striking color changes... 520 00:46:20,280 --> 00:46:22,320 ...during the seasons. 521 00:46:38,240 --> 00:46:42,640 Others, like the holm oaks and pine forests... 522 00:46:42,760 --> 00:46:46,640 ...maintain their eternal green all year. 523 00:46:49,480 --> 00:46:53,520 Inside the forest they live infinity of living beings... 524 00:46:53,680 --> 00:46:55,800 ...hundreds of lichens and fungi... 525 00:46:55,920 --> 00:46:59,680 ...they grow on logs and on the ground. 526 00:47:02,200 --> 00:47:03,920 And they raise multitudes of birds... 527 00:47:04,040 --> 00:47:07,400 ...although it is easier hear them than see them. 528 00:47:07,840 --> 00:47:11,280 There are times when the varied song of the birds... 529 00:47:11,480 --> 00:47:13,800 ...looks like an orchestrated concert. 530 00:47:15,160 --> 00:47:19,560 And others, where silence reigns. 531 00:47:22,960 --> 00:47:26,360 A male goshawk perches on a recently fallen pine tree. 532 00:47:27,600 --> 00:47:30,440 He moves through the forest like a ghost. 533 00:47:31,720 --> 00:47:33,800 He looks like he wears a prey with me... 534 00:47:33,920 --> 00:47:38,040 ...could be a jay, one of his favorite prey. 535 00:47:39,480 --> 00:47:42,280 He doesn't taste a single bite. 536 00:47:42,440 --> 00:47:46,200 wait for someone and demands his attention. 537 00:47:51,640 --> 00:47:53,240 Here she is. 538 00:47:53,640 --> 00:47:56,320 He dodges her, she has been very close to her. 539 00:47:59,240 --> 00:48:03,000 The female quickly goes to the nest, she has no time to lose... 540 00:48:03,760 --> 00:48:05,960 ... her three chickens just 22 days... 541 00:48:06,080 --> 00:48:10,600 ...are hungry and every day They demand more food. 542 00:48:13,320 --> 00:48:14,760 During the breeding season... 543 00:48:14,880 --> 00:48:18,400 ...the male takes care to capture prey. 544 00:48:18,880 --> 00:48:20,560 As soon as it's done with a... 545 00:48:20,680 --> 00:48:22,960 ...come quickly to the exchange area... 546 00:48:23,080 --> 00:48:25,120 ...and calls his partner. 547 00:48:25,280 --> 00:48:26,800 She jumps out of the nest... 548 00:48:26,920 --> 00:48:29,760 ...and in a matter of seconds she introduces herself next to the male. 549 00:48:30,040 --> 00:48:32,880 He catches the prey, but this time he doesn't leave... 550 00:48:33,000 --> 00:48:37,480 ...he stays to fleece her here before taking her to the nest. 551 00:48:37,840 --> 00:48:42,320 It is the mother who awakens and she feeds the chickens. 552 00:48:46,240 --> 00:48:49,200 after ten days, we found no one in the nest. 553 00:48:50,520 --> 00:48:53,840 And it's still early for them to have flown. 554 00:48:58,040 --> 00:49:00,920 They're here, they had not disappeared. 555 00:49:02,120 --> 00:49:03,800 They are flyers. 556 00:49:04,080 --> 00:49:06,480 They went up through the different branches of the tree... 557 00:49:06,600 --> 00:49:11,200 ...and they train their muscles for when they jump out of the nest. 558 00:49:22,040 --> 00:49:24,280 Now that the chickens they are bigger... 559 00:49:24,400 --> 00:49:27,680 ...the parents take them the unplucked prey... 560 00:49:27,800 --> 00:49:30,160 ...and they are the ones in charge to share the food. 561 00:49:33,080 --> 00:49:37,000 The two females engage in a fight, both are hungry. 562 00:49:41,160 --> 00:49:42,920 Brother is late... 563 00:49:43,280 --> 00:49:46,520 ... but he already knows that he doesn't have much to do... 564 00:49:46,640 --> 00:49:49,160 ...You have to wait for her sisters to finish eating. 565 00:49:49,480 --> 00:49:51,200 They are bigger... 566 00:49:51,320 --> 00:49:55,520 ...and her aggressive character is defined since they are very young. 567 00:49:56,880 --> 00:50:01,400 Although they already know how to fly They are not yet independent. 568 00:50:01,520 --> 00:50:03,200 For another two or three months... 569 00:50:03,320 --> 00:50:06,480 ...will follow closely the footsteps of their parents. 570 00:50:06,600 --> 00:50:10,360 They will teach you the best hunting techniques... 571 00:50:10,480 --> 00:50:13,520 ...and how to be the ghost of the forest 572 00:50:13,880 --> 00:50:15,160 But until then... 573 00:50:15,280 --> 00:50:17,920 ...They will continue to come to the feeding point... 574 00:50:18,040 --> 00:50:20,200 ...where the father brings them food. 575 00:50:25,040 --> 00:50:26,880 Forests harbor... 576 00:50:27,000 --> 00:50:30,080 ...a very important part of biodiversity... 577 00:50:30,400 --> 00:50:32,280 ...contribute to soil protection... 578 00:50:32,400 --> 00:50:34,280 ...and regulate the global climate... 579 00:50:34,400 --> 00:50:36,840 ...being an important carbon reservoir. 580 00:50:42,240 --> 00:50:45,120 In our environment stand out some like the one from lrati... 581 00:50:45,240 --> 00:50:48,000 ...which is the

726 01:02:34,080 --> 01:02:37,480 ...so that the inhabitants of the forest can take advantage of these resources... 727 01:02:37,600 --> 01:02:39,240 ...that wood offers. 728 01:02:46,920 -->

value. 731 01:02:59,240 --> 01:03:01,720 A value, which is increased... 732 01:03:01,840 --> 01:03:04,920 ...depending of its geographical location. 733 01:03:07,560 --> 01:03:09,520 During the winter months... 734 01:03:09,800 --> 01:03:11,520 ...large flocks of starlings... 735 01:03:11,640 --> 01:03:16,000 ...They are grouped around the lagoons from La Guardia and Las Cañas. 736 01:03:17,920 --> 01:03:21,400 It is usual to count hundreds of thousands of them. 737 01:03:28,120 --> 01:03:33,280 A falcon approaches and the group stretches and divides. 738 01:03:37,360 --> 01:03:41,360 they know very well what to do when someone is chasing them. 739 01:03:46,320 --> 01:03:50,000 They are able to create unlikely shapes in the air... 740 01:03:50,240 --> 01:03:53,640 ...and this makes it difficult to predators. 741 01:03:55,480 --> 01:03:58,120 The tactic of the starlings is clear: 742 01:03:58,240 --> 01:04:00,720 ...have to stick together. 743 01:04:01,200 --> 01:04:03,280 The group gives them security... 744 01:04:03,400 --> 01:04:07,000 ...and if they have to closely mark your opponent... 745 01:04:07,120 --> 01:04:08,680 ...they do. 746 01:04:10,480 --> 01:04:12,680 But there is also a goshawk. 747 01:04:14,320 --> 01:04:17,280 starlings They don't let them get away. 748 01:04:17,560 --> 01:04:21,760 They are so many that the raptors They don't know where to attack them. 749 01:04:24,880 --> 01:04:26,040 Nonetheless... 750 01:04:26,160 --> 01:04:29,800 ...predators have your strategy well prepared... 751 01:04:29,920 --> 01:04:31,400 ...and they are very capable... 752 01:04:31,520 --> 01:04:35,120 ...To carry the choreography of the starlings to the limit. 753 01:04:38,280 --> 01:04:41,840 Among many, there is always some low. 754 01:04:43,800 --> 01:04:47,120 form large groups It gives them more protection... 755 01:04:47,240 --> 01:04:50,840 ...but in turn, makes them more visible. 756 01:04:58,600 --> 01:05:03,280 This is the Pitillas Lagoon, in the center of Navarre. 757 01:05:03,880 --> 01:05:07,840 surrounded by steppes and with a Mediterranean climate... 758 01:05:08,120 --> 01:05:09,520 ...rainfall... 759 01:05:09,640 --> 01:05:11,800 ...for much of the year they are scarce... 760 01:05:12,200 --> 01:05:13,640 ...so the lagoon... 761 01:05:13,760 --> 01:05:17,480 ...It is of vital importance for wildlife. 762 01:05:22,760 --> 01:05:24,240

01:07:25,680 --> 01:07:29,640 These beautiful and colorful birds spend the winter in Africa... 777 01:07:30,080 --> 01:07:34,680 ...and travel more than 7000 km to come here to breed. 778 01:07:36,600 --> 01:07:38,200 It is in this area where they find... 779 01:07:38,320 --> 01:07:40,640 ...food and tranquility what do you need. 780 01:07:46,840 --> 01:07:48,320 Agile and fast... 781 01:07:48,440 --> 01:07:50,840 ...they pursue their prey in flight... 782 01:07:50,960 --> 01:07:53,480 ...until, finally, they manage to reach them. 783 01:08:07,240 --> 01:08:09,160 Sometimes for themselves... 784 01:08:10,000 --> 01:08:12,880 ...And other times for your partner. 785 01:08:20,600 --> 01:08:23,560 The male usually does offerings to the female... 786 01:08:23,680 --> 01:08:26,560 ...although this one doesn't seem be too clear. 787 01:08:29,680 --> 01:08:33,560 He tries it with another but he is not convinced either. 788 01:08:34,240 --> 01:08:37,400 It looks like it is, but he doesn't want to give it to her. 789 01:08:38,320 --> 01:08:40,720 Neither now... 790 01:08:42,400 --> 01:08:45,160 In the end The female gets the gift from her... 791 01:08:45,280 --> 01:08:47,200 ...but she decides to leave. 792 01:08:47,920 --> 01:08:51,560 so many insecurities They have not been to his liking. 793 01:09:12,560 --> 01:09:13,760 The European pond turtle is... 794 01:09:13,880 --> 01:09:17,800 ...of the few native turtles that we still have. 795 01:09:18,440 --> 01:09:21,600 much of his life spends it in the water... 796 01:09:24,800 --> 01:09:28,120 ...but is able to traverse long distances overland... 797 01:09:28,240 --> 01:09:30,600 ...in search of their next destination. 798 01:09:37,480 --> 01:09:40,760 in Navarre, have been recorded... 799 01:09:40,880 --> 01:09:42,320 ...upper courses four kilometers... 800 01:09:42,440 --> 01:09:45,200 ...Without mediating any pond in the middle. 801 01:09:57,040 --> 01:09:59,200 the clouds follow his way south... 802 01:09:59,320 --> 01:10:02,080 ...Each time with less water; 803 01:10:03,560 --> 01:10:06,080 ...and this shows... 804 01:10:06,680 --> 01:10:08,280 ...Since they exist places in Navarre... 805 01:10:08,400 --> 01:10:10,840 ...where I could almost talk about deserts. 806 01:10:12,840 --> 01:10:15,120 here, it is not uncommon that temperatures... 807 01:10:15,240 --> 01:10:19,200 ...reach 40 during the summer months... 808 01:10:19,640 --> 01:10:23,080 ...and collapse during the winter months. 809 01:10:26,000 --> 01:10:29,720 We just got into a of the largest Iberian steppes... 810 01:10:29,840 --> 01:10:31,600 ...the Bardenas Reales. 811 01:10:38,520 --> 01:10:41,480 Located southeast of Navarra... 812 01:10:41,600 --> 01:10:45,280 ...what in earlier times became an inland sea... 813 01:10:45,400 --> 01:10:46,480 ...it's today... 814 01:10:46,600 --> 01:10:50,200 ...a huge set of formations mainly clay... 815 01:10:50,400 --> 01:10:52,960 ...with plaster and sandstone. 816 01:10:56,600 --> 01:10:58,960 These sedimented materials... 817 01:10:59,200 --> 01:11:00,760 ...have come to create... 818 01:11:00,880 --> 01:11:04,200 ...vertiginous forms and of unusual beauty... 819 01:11:04,320 --> 01:11:06,840 ...sculpted by wind and water 820 01:11:24,240 --> 01:11:27,440 The land that makes up the Bardena it is easy to erode... 821 01:11:27,800 --> 01:11:31,360 ...and many animals seek shelter underground. 822 01:11:36,320 --> 01:11:38,760 This hole we see in the ground, has built... 823 01:11:38,880 --> 01:11:42,400 ...A stone wall and sticks around it. 824 01:11:44,560 --> 01:11:47,000 could be home of this firefly... 825 01:11:49,280 --> 01:11:51,000 ...but it seems not. 826 01:11:51,120 --> 01:11:53,600 Pass by and continue on your way. 827 01:11:56,120 --> 01:11:59,000 Or will it be the hiding place of this cricket? 828 01:12:01,160 --> 01:12:04,480 Just entered the territory of the Iberian tarantula. 829 01:12:05,080 --> 01:12:08,040 Grab the cricket with its legs and bites him. 830 01:12:08,400 --> 01:12:12,680 he resists, but he can do little. 831 01:12:13,640 --> 01:12:17,240 The tarantula has inoculated him the paralyzing poison of him. 832 01:12:23,080 --> 01:12:26,320 Despite being an animal nocturnal habits... 833 01:12:26,440 --> 01:12:30,680 ...always stay alert to act before any movement 834 01:12:38,320 --> 01:12:41,200 In the extensive cultivated areas from the surroundings of the Bardena... 835 01:12:41,320 --> 01:12:44,400 ...it is still possible to see some great bustard 836 01:12:45,600 --> 01:12:46,840 These great birds... 837 01:12:46,960 --> 01:12:49,440 ...are at the limit of his ability to fly... 838 01:12:50,120 --> 01:12:52,200 ...and they hold the record for being... 839 01:12:52,640 --> 01:12:55,360 ...the flying species heaviest in Europe. 840 01:12:56,280 --> 01:12:57,360 The males... 841 01:12:57,800 --> 01:13:02,560 ...can weigh, in some cases, up to 24 kg 842 01:13:10,360 --> 01:13:13,440 During oestrus, males court females... 843 01:13:13,560 --> 01:13:16,000 ...carrying out moves called wheel... 844 01:13:18,120 --> 01:13:19,800 ...and transform his suit of feathers... 845 01:13:19,920 --> 01:13:24,440 ...in an elegant ball gown, suitable for the occasion. 846 01:13:29,600 --> 01:13:32,600 is now when it begins its media deployment... 847 01:13:33,080 --> 01:13:37,000 ...for the sole purpose to attract a potential mate. 848 01:13:43,400 --> 01:13:45,120 There are very few. 849 01:13:46,040 --> 01:13:50,520 In 2000 km² it is only possible locate 21 specimens. 850 01:13:51,840 --> 01:13:54,160 They are running out of habitat... 851 01:13:54,280 --> 01:13:56,240 ...And Ribera Navarra is... 852 01:13:56,360 --> 01:13:57,880 ...ITS northern boundary of distribution... 853 01:13:58,000 --> 01:14:00,000 ...within the Iberian Peninsula. 854 01:14:00,440 --> 01:14:02,640 Further north they do not inhabit. 855 01:14:04,000 --> 01:14:05,360 Nevertheless... 856 01:14:05,480 --> 01:14:08,760 ...the species will keep trying pass on their genes... 857 01:14:08,880 --> 01:14:10,720 ...over time. 858 01:14:28,560 --> 01:14:30,840 Summers are dry... 859 01:14:31,480 --> 01:14:37,440 ...And it can take several weeks without even a drop of rain falling. 860 01:14:41,000 --> 01:14:44,280 So the water becomes in the most precious element... 861 01:14:44,400 --> 01:14:46,400 ...for the inhabitants of the area. 862 01:14:49,280 --> 01:14:51,880 we can find it in very few places... 863 01:14:52,000 --> 01:14:54,840 ...on some channels and scattered ponds. 864 01:15:00,240 --> 01:15:01,160 Many times... 865 01:15:01,280 --> 01:15:05,440 ...from one point to another There are usually long distances. 866 01:15:05,720 --> 01:15:08,560 This determines that each individual and family... 867 01:15:08,760 --> 01:15:11,520 ...have always the same place of reference... 868 01:15:11,640 --> 01:15:13,040 ...to go to. 869 01:15:18,360 --> 01:15:21,520 A bird that blends perfectly with the environment... 870 01:15:21,640 --> 01:15:24,040 ...It emerges from the vegetation. 871 01:15:24,400 --> 01:15:26,560 It's a bargain ortega. 872 01:15:28,360 --> 01:15:30,200 And she doesn't come alone. 873 01:15:31,360 --> 01:15:34,280 in the middle distance His family and relatives follow him... 874 01:15:34,960 --> 01:15:36,840 ...the Iberian bargains. 875 01:15:38,680 --> 01:15:42,600 These steppe birds gather in bands every morning. 876 01:15:43,360 --> 01:15:45,920 It is safer in a large group 877 01:15:46,200 --> 01:15:48,640 They move cautiously through the vegetation. 878 01:15:50,680 --> 01:15:54,640 They are in a hurry to arrive but they rarely show it. 879 01:15:56,440 --> 01:15:59,480 In the destiny there could be some predator... 880 01:15:59,600 --> 01:16:02,280 ...so that, any precaution is little. 881 01:16:03,160 --> 01:16:05,960 better be do things carefully... 882 01:16:11,320 --> 01:16:14,280 At last, They have already reached their destination. 883 01:16:15,160 --> 01:16:18,120 A pond that still holds water. 884 01:16:18,760 --> 01:16:22,720 Bargains from all over the area will continue coming here during the summer. 885 01:16:23,280 --> 01:16:27,240 One of them cheers and the others follow. 886 01:16:28,360 --> 01:16:29,600 But some decide... 887 01:16:29,720 --> 01:16:32,760 ...that the best thing is to get involved directly into the pond. 888 01:16:33,240 --> 01:16:35,840 Thus, their feathers fill with water... 889 01:16:35,960 --> 01:16:38,880 ...And they can give drink to their chicks. 890 01:16:39,120 --> 01:16:43,680 Although in this family they already drink by themselves. 891 01:16:46,960 --> 01:16:49,360 Once they quench their thirst and have absorbed... 892 01:16:49,480 --> 01:16:52,520 ...as much water as possible in their feathers... 893 01:16:52,640 --> 01:16:55,360 ...They march a little faster from which they have come... 894 01:16:55,480 --> 01:16:57,520 ...but with the same precautions. 895 01:17:02,480 --> 01:17:04,280 One of the chickens approaches... 896 01:17:04,400 --> 01:17:05,960 ...he hangs his head... 897 01:17:06,080 --> 01:17:09,880 ...And he drinks a few drops that his father carries in his feathers. 898 01:17:12,440 --> 01:17:14,920 Until they gain greater autonomy... 899 01:17:15,040 --> 01:17:17,280 ...They will continue to make this gesture... 900 01:17:17,400 --> 01:17:21,200 ...and thus strengthening their family union. 901 01:17:25,240 --> 01:17:28,480 Iberian gangas and ortegas, They are steppe birds... 902 01:17:28,600 --> 01:17:31,640 ...that are found in danger of extinction. 903 01:17:33,080 --> 01:17:37,320 agrarian intensification landscape is changing... 904 01:17:37,840 --> 01:17:40,000 ...and leaving these beautiful birds typical of our land... 905 01:17:40,120 --> 01:17:41,880 ...on the verge of disappearance. 906 01:17:49,400 --> 01:17:50,520 The truth is... 907 01:17:50,640 --> 01:17:54,000 ...although it is a territory small and crowded... 908 01:17:54,120 --> 01:17:57,720 ...the flora and fauna they harbor Euskadi and Navarre... 909 01:17:57,840 --> 01:18:01,040 ...has a high value ecological and natural. 910 01:18:01,440 --> 01:18:03,240 Many times We are not aware... 911 01:18:03,600 --> 01:18:06,720 ...but all these species and many more... 912 01:18:06,840 --> 01:18:08,840 ...live close to us... 913 01:18:09,200 --> 01:18:11,560 ...And they have an important job... 914 01:18:11,680 --> 01:18:15,760 ...within the complex framework that make up an ecosystem. 915 01:18:18,680 --> 01:18:20,960 A well-preserved habitat... 916 01:18:21,080 --> 01:18:25,560 ...means greater biological diversity and, therefore... 917 01:18:25,680 --> 01:18:28,400 ...higher quality in everyone's life. 918 01:18:31,120 --> 01:18:33,560 Nature doesn't need us... 919 01:18:33,960 --> 01:18:36,560 ...But we we do need her. 920 01:18:39,080 --> 01:18:41,800 Currently the story continues... 921 01:18:41,920 --> 01:18:46,400 ...unstoppable, evolution keep working tirelessly... 922 01:18:46,520 --> 01:18:49,240 ...working with time new ways... 923 01:18:49,360 --> 01:18:52,840 ...although the transformations that they may come are unexpected; 924 01:18:53,600 --> 01:18:56,400 ...like climate change. 925 01:18:57,920 --> 01:19:01,560 some species They will improve their situation... 926 01:19:01,680 --> 01:19:04,440 ...and others will disappear... 927 01:19:04,880 --> 01:19:08,360 ...But while natural life continues to exist... 928 01:19:08,560 --> 01:19:11,960 ...natural selection will continue modeling... 929 01:19:12,080 --> 01:19:16,120 ...this important heritage what we call biodiversity.
