reflected off the river

00:15:11,120 --> 00:15:12,000

193

to the place their parents emerged.

00:43:13,400 --> 00:43:17,440
The spectacular cloud forests
of the Talamanca mountains.
533
00:43:25,000 --> 00:43:28,000
Rising in places to over 3,500m...
534
00:43:28,000 --> 00:43:28,960
Rising in places to over 3,500m...
535
00:43:30,040 --> 00:43:34,800
..their lush vegetation is a welcome
sight for one tiny traveller.
536
00:43:44,560 --> 00:43:46,680
(HUMMINGBIRD CHIRPS)
537
00:43:47,720 --> 00:43:50,000
A fiery-throated hummingbird.
538
00:43:53,800 --> 00:43:56,000
It's the start of the rainy season,
539
00:43:56,040 --> 00:43:58,280
when there's a fresh flush of growth
540
00:43:58,320 --> 00:44:00,000
and she's come up to these cool
mountain forests to look for food.
541
00:44:00,000 --> 00:44:01,840
and she's come up to these cool
mountain forests to look for food.
542
00:44:20,040 --> 00:44:22,920
She's one of the most stunning
of all birds,
543
00:44:22,960 --> 00:44:24,000
with every shade of the rainbow on
her iridescent throat and chest.
544
00:44:24,000 --> 00:44:27,040
with every shade of the rainbow on
her iridescent throat and chest.
545
00:44:28,200 --> 00:44:30,560
She's also one of the busiest.
546
00:44:32,840 --> 00:44:34,280
To power her wings
547
00:44:34,320 --> 00:44:38,160
she has to sip nectar
up to 2,000 times a day.
548
00:44:40,840 --> 00:44:42,720
Just two hours without food
549
00:44:42,760 --> 00:44:45,120
and she'll be on the brink
of starvation.
550
00:44:47,040 --> 00:44:48,000
So, in this new patch of forest
551
00:44:48,000 --> 00:44:49,120
So, in this new patch of forest
552
00:44:49,160 --> 00:44:51,120
she must find the flowers quickly
553
00:44:51,160 --> 00:44:53,280
and learn the shortest routes
between them.
554
00:44:59,720 --> 00:45:03,480
And in doing this,
she's extraordinarily acrobatic.
555
00:45:16,040 --> 00:45:19,520
Like all hummingbirds,
she can fly straight up...
556
00:45:20,760 --> 00:45:22,200
..even backwards.
557
00:45:22,920 --> 00:45:25,160
They're the only bird to do so.
558
00:45:27,640 --> 00:45:28,000
This versatility is down to the
remarkable way she uses her wings.
559
00:45:28,000 --> 00:45:32,000
This versatility is down to the
remarkable way she uses her wings.
560
00:45:37,080 --> 00:45:38,880
A special shoulder joint
561
00:45:38,920 --> 00:45:42,080
allows her to rotate
her wings in a figure of eight.
562
00:45:48,400 --> 00:45:50,280
Rather than flap them
563
00:45:50,320 --> 00:45:51,880
she twists them.
564
00:46:00,920 --> 00:46:04,360
And by beating her wings
up to 30 times a second
565
00:46:04,400 --> 00:46:05,880
she can hover...
566
00:46:08,000 --> 00:46:11,920
..holding herself steady when
feeding, with remarkable precision.
567
00:46:19,720 --> 00:46:22,160
Having sipped from each bloom here,
568
00:46:22,200 --> 00:46:24,000
her search for food continues.
569
00:46:24,000 --> 00:46:24,640
her search for food continues.
570
00:46:41,760 --> 00:46:43,280
(HUMMINGBIRD CHIRPS)
571
00:46:50,400 --> 00:46:53,400
But this sweet nectar
is in high demand...
572
00:46:56,120 --> 00:46:58,920
..and this patch of forest is taken.
573
00:47:05,880 --> 00:47:08,920
Another fiery-throated hummingbird.
574
00:47:09,800 --> 00:47:12,000
He wants all the flowers to himself
575
00:47:12,040 --> 00:47:14,680
and he's prepared to fight her off.
576
00:47:19,080 --> 00:47:20,000
(CHIRPING AGGRESSIVELY)
577
00:47:20,000 --> 00:47:20,560
(CHIRPING AGGRESSIVELY)
578
00:47:24,400 --> 00:47:26,960
But she's determined
to stand her ground.
579
00:47:37,600 --> 00:47:39,840
In their attempts to overpower
each other,
580
00:47:39,880 --> 00:47:42,480
they use all their acrobatic skills.
581
00:47:54,080 --> 00:47:56,120
Her opponent gains the advantage.
582
00:48:03,640 --> 00:48:06,560
Using his wings now as weapons
583
00:48:06,600 --> 00:48:08,000
he tries to disorientate her.
584
00:48:08,000 --> 00:48:08,600
he tries to disorientate her.
585
00:48:11,840 --> 00:48:13,960
But she's not giving up.
586
00:48:21,440 --> 00:48:24,000
And finally, she sees him off.
587
00:48:24,000 --> 00:48:24,040
And finally, she sees him off.
588
00:48:36,120 --> 00:48:37,680
She claims her patch...
589
00:48:44,600 --> 00:48:46,360
..and takes her reward.
590
00:49:14,960 --> 00:49:19,400
Animals all over the world have risen
to an extraordinary challenge.
591
00:49:21,640 --> 00:49:23,560
And defied gravity.
592
00:49:25,680 --> 00:49:28,000
With ingenuity and determination...
593
00:49:28,000 --> 00:49:28,400
With ingenuity and determination...
594
00:49:29,560 --> 00:49:31,360
..they've taken the fight,
595
00:49:31,400 --> 00:49:33,440
to survive and thrive,
596
00:49:33,480 --> 00:49:35,360
to a whole new level...
597
00:49:38,720 --> 00:49:40,600
..earning their place
598
00:49:40,640 --> 00:49:43,120
as rulers of the skies.
599
00:49:53,040 --> 00:49:55,880
To film the heaviest soaring bird
in the world
600
00:49:55,920 --> 00:49:59,720
the Airborne team undertake
a three-day journey from the UK
601
00:49:59,760 --> 00:50:00,000
to a remote part of Patagonia,
in Chile.
602
00:50:00,000 --> 00:50:03,360
to a remote part of Patagonia,
in Chile.
603
00:50:07,440 --> 00:50:08,000
The location - a protected site
over 1,000m high
604
00:50:08,000 --> 00:50:11,640
The location - a protected site
over 1,000m high
605
00:50:11,680 --> 00:50:13,280
in the Andean foothills -
606
00:50:13,320 --> 00:50:15,320
is not for the faint hearted.
607
00:50:18,040 --> 00:50:19,960
But these precipitous cliffs
608
00:50:20,000 --> 00:50:22,240
are perfect for condors.
609
00:50:23,280 --> 00:50:24,000
Wow. What an amazing place.
610
00:50:24,000 --> 00:50:25,560
Wow. What an amazing place.
611
00:50:26,440 --> 00:50:28,720
It's difficult to get to,
but my goodness.
612
00:50:31,120 --> 00:50:32,000
I've never seen so many condors.
613
00:50:32,000 --> 00:50:33,000
I've never seen so many condors.
614
00:50:38,560 --> 00:50:40,000
There's one about to come overhead.
615

There's one about to come overhead.
616
00:50:42,200 --> 00:50:43,840
Look at that.
617
00:50:43,880 --> 00:50:46,800
(CHUCKLES) They're amazing.
618
00:50:48,720 --> 00:50:51,040
With condors soaring all around them
619
00:50:51,080 --> 00:50:53,080
the team are eager to start filming.
620
00:50:55,080 --> 00:50:56,000
To capture their behaviour
621
00:50:56,000 --> 00:50:57,120
To capture their behaviour
622
00:50:57,160 --> 00:50:59,320
wildlife cameraman James Aldred
623
00:50:59,360 --> 00:51:02,240
is going to have to take his life in
his hands.
624
00:51:07,800 --> 00:51:10,680
I'm gonna take a couple of these
slings as well, actually.
625
00:51:15,960 --> 00:51:18,120
As a professional rope technician
626
00:51:18,160 --> 00:51:20,000
he's qualified to assess exactly
where it's safe
627
00:51:20,000 --> 00:51:20,920
he's qualified to assess exactly
where it's safe
628
00:51:20,960 --> 00:51:23,080
to get a clear view of the condors.
629
00:51:25,960 --> 00:51:28,000
But even he can find
these heights scary.
630
00:51:28,000 --> 00:51:28,920
But even he can find
these heights scary.
631
00:51:29,920 --> 00:51:32,080
So if I haven't been up high
for a while
632
00:51:32,120 --> 00:51:35,120
I definitely feel a little bit weird
looking over the edge.
633
00:51:36,640 --> 00:51:38,600
Having chosen his spot,
634
00:51:38,640 --> 00:51:40,560
he sets up his safety ropes.
635
00:51:51,640 --> 00:51:52,000
It's incredibly dramatic.
636
00:51:52,000 --> 00:51:53,400
It's incredibly dramatic.
637
00:51:54,560 --> 00:51:57,760
You know, if I was gonna imagine
where condors would hang out
638
00:51:57,800 --> 00:51:58,960
this is pretty much it.
639
00:51:59,000 --> 00:52:00,000
I mean, it wouldn't look out of
place to see a dragon
640
00:52:00,000 --> 00:52:01,240
I mean, it wouldn't look out of
place to see a dragon
641
00:52:01,280 --> 00:52:03,200
perched on top of some
of these ridges.
642
00:52:03,240 --> 00:52:06,520
It's a hell of a spot. I love it
here. Absolutely love it.
643
00:52:08,160 --> 00:52:09,680
For the next few weeks
644
00:52:09,720 --> 00:52:11,400
the team set up before dawn...
645
00:52:12,880 --> 00:52:16,000
..hoping to catch the condor's first
flight of the day.

Local drone operator,
Cristobal Santamaria,
648
00:52:32,560 --> 00:52:35,880
has been tasked with capturing close,
immersive shots
649
00:52:35,920 --> 00:52:37,520
of these birds in flight.
650
00:52:38,920 --> 00:52:40,000
CRISTOBAL: Woo-hoo! We have condors.
651
00:52:40,000 --> 00:52:41,480
CRISTOBAL: Woo-hoo! We have condors.
652
00:52:47,320 --> 00:52:48,000
But here in Patagonia,
there's a saying:
653
00:52:48,000 --> 00:52:50,000
But here in Patagonia,
there's a saying:
654
00:52:50,040 --> 00:52:52,200
four seasons in a day.
655
00:52:52,240 --> 00:52:53,960
As soon as the sun's up
656
00:52:54,000 --> 00:52:55,640
the wind picks up, too.
657
00:52:57,240 --> 00:52:59,360
Now, the wind is too strong.
658
00:53:00,400 --> 00:53:02,920
He makes the call to bring
back the drone.
659
00:53:05,480 --> 00:53:07,640
(WIND HOWLING)
Oh, hold on.
660
00:53:09,000 --> 00:53:10,240
Can you work it?
661
00:53:25,000 --> 00:53:26,320
(EXHALES)
662
00:53:27,480 --> 00:53:28,000
With the drone back on terra firma...
663
00:53:28,000 --> 00:53:29,800
With the drone back on terra firma...
664
00:53:31,040 --> 00:53:33,440
..down in a more sheltered
roost site,
665
00:53:33,480 --> 00:53:36,000
James is capturing some
extraordinary behaviour.
666
00:53:36,000 --> 00:53:36,440
James is capturing some
extraordinary behaviour.
667
00:53:39,640 --> 00:53:41,960
A black-chested buzzard eagle
668
00:53:42,000 --> 00:53:43,400
defending her territory.
669
00:53:45,160 --> 00:53:48,040
I was filming it in slow-mo,
five times slowed down.
670
00:53:48,080 --> 00:53:50,400
When it happens in real life
it's bang!
671
00:53:54,080 --> 00:53:55,880
Oh, my goodness!
672
00:53:55,920 --> 00:53:58,320
Absolutely amazing! (CHUCKLES)
673
00:54:00,640 --> 00:54:04,680
Rarely witnessed, this aggressive
behaviour towards condors
674
00:54:04,720 --> 00:54:06,840
has never been broadcast before.
675
00:54:09,200 --> 00:54:12,280
After three weeks, the team have
achieved what they came for...
676
00:54:13,160 --> 00:54:15,920
..and will be sad to leave
this thriving colony.
677
00:54:16,520 --> 00:54:18,920
RENE: So, yes, the numbers
are healthy here.
678
00:54:18,960 --> 00:54:22,080
It doesn't mean that the animal
is healthy as a population
679
00:54:22,120 --> 00:54:24,000
in general. It's struggling
in other places.
680
00:54:24,000 --> 00:54:25,040
in general. It's struggling
in other places.
681
00:54:26,240 --> 00:54:29,400
And we are very lucky to see
condors, as we can see them here.
682
00:54:29,440 --> 00:54:31,560
This is not something normal
or common.
683
00:54:31,600 --> 00:54:32,000
Even us, being from Chile,
this is not something
684
00:54:32,000 --> 00:54:34,640
Even us, being from Chile,
this is not something
685
00:54:34,680 --> 00:54:36,400
that you get to see every day.
686
00:54:39,600 --> 00:54:40,000
They'll take away a deeper respect
687
00:54:40,000 --> 00:54:42,160
They'll take away a deeper respect
688
00:54:42,200 --> 00:54:44,360
for these remarkable birds.
