Life in the wild is tough.

Animals sometimes have to pull out all the stops to survive.

And while some play by the rules,

others, it seems, are more than happy to break them.

The natural world is full of animals who are up to no good.

They're stealing.

Vandalising.

Fighting.

And even kidnapping.

But is this really as appalling as it looks?

I'm travelling the planet

to witness some of these animal antics first-hand...

They are very cheeky, very cheeky.

..meeting the experts making groundbreaking new discoveries...

That's mad!

..and finding out for myself

if what appears to be bad behaviour

may just be the secret

to their success.

I'm really beginning to love these guys.

That's just clever and funny.

But we need our camera back.

Next on my journey, I'm discovering

just how far some creatures will go to find food.

I'm going to introduce you to the extraordinary animals

who will stop at nothing to get a good meal.

Every day, animals face

one of life's greatest challenges.

Finding food.

But getting your share is never easy.

On one of Australia's most remote outposts,

one animal's search for sustenance is causing trouble for the locals.

MAN: When I first arrived at the island,

in the middle of the night, you'd hear knocks and scratches,

and some people think the place is haunted.

MAN: I just left my bag on the ground,

like you normally would anywhere else.

Go for a walk that way, you come back. "Where's my bag?"

He's gotten it open.

There's a camera that's now over there

and he's got my drink bottle.

He's clawing at the lid, just trying to get in.

I've come to meet the creature

behind this crime wave.

This magnificent animal

is the coconut crab,

the world's largest land crab.

It's been known to grow as long

as half a metre in length

and can be as heavy as four kilos.

I mean, just look at it.

These giants are equipped with formidable armour

and claws powerful enough to tear open a coconut.

Here on Christmas Island, there are over a million of them.

That's 500 crabs for every human.

And they all need to eat.

So, every opportunity is fair game.

These crabs are doing something a little bit unexpected.

They've turned to a life of crime.

In fact, to the locals here, they're known as robber crabs.

We'd find the crabs

were stealing our lunch every time we left it alone.

They can get into cool-boxes, they can cut through plastic,

they can cut through metal.

We were down at Dolly Beach

and we were opening some coconuts with a machete.

We just put the machete down for a second, walked away,

and when we came back, the robber crab

was walking off with the machete.

These daring thieves are taking everything that isn't nailed down.

Stories abound all over Christmas Island

of coconut crabs stealing non-food items.

They pinch shoes off porches,

shiny things like cutlery.

There's even a story of a coconut crab

taking a gun off a military guard.

But why would crabs nick things they can't even eat?

I want to see what they get up to for myself,

so I'm setting a trap using some everyday objects

and motion-sensor cameras

to catch the crabs in the act.

OK.

The next morning, I return with Max Orchard,

an expert in coconut crab behaviour,

to look over what we filmed.

OK, let's have a look...

..at what these coconut crabs have been up to.

MAX: Mm hmm.

LIZ: Oh!

MAX: Uh-huh.

First of all, the antennae make an appearance.

Flip-flop, bosh!

Cheeky crab. He's having that.

The footage reveals that up to 10 different crabs

investigated the items.

It was busy here last night, wasn't it?

Max...Ma...! Look at this!

That's... Wow.

Taking the camera.

And he has been so obliging by lighting himself,

triggering the camera.

Oh, that's just brilliant to see.

Max, what is it all about?

Why would they be so interested in non-food items?

They come across things that they don't know,

but they check them out - they may be able to eat them.

And is it always about food?

It's the driving force.

If things are out in the open,

they like to grab them and then cart off.

And if they are edible, chew them,

without other crabs trying to steal them from them.

Somewhere out here, there's a crab sitting on my camera.

With so many crabs on the island,

the competition for food is intense,

which means they'll check out anything new

to see if they can eat it.

Well, I can see a crab in there and I can see the flip flop.

And because they take these items somewhere safe to investigate them,

it looks, to us, like theft.

(GASPS) Right, OK, look, that's...

..that's a piece of the camera there, look.

I'm really beginning to love these guys.

That's just clever and funny.

But we need our camera back.

It's not that funny, then.

But there is one thing this doesn't explain.

Coconut crabs seem to show up from nowhere

as soon as a new item appears.

A somewhat surprising skill for a crustacean.

So, how does a crab hone in so superbly well

on the items it's interested in?

Max has been helping scientists to find the answer.

And it's all down to one of their incredible sensors.

To show me, he's positioned one of their favourite foods, a coconut,

off the ground,

alongside some empty control poles.

With the raised bait harder to see,

do the crabs need to rely on something other than sight?

It's only a matter of minutes before they appear.

Now, I can see that it's waving its antennae around.

What's going on there.

The ones that you can see waving

are actually their equivalent of our nose.

They pick up the scent in the air

and then it's transmitted to the brain.

- So, he's having a good smell. - He is.

He's getting a whiff of that coconut.

As they evolved to live on land,

these crabs developed an incredibly effective way

of detecting smells in the air,

as opposed to underwater.

The tips of their inner antennae are covered with thin hairs

detecting chemicals from any item with a scent.

The robber crabs can pick up distinct aromas

from over 150 metres away...

That far?

..and actually change course in their wanderings through the bush

to track down the source of those smells.

They can even detect residual scent.

Anything that's previously come into contact with the food

and even other smells like sweat

can grab their attention.

Which is why they seem to appear out of nowhere for any object.

And why they make light work

of honing in on their favourite food.

He's making a beeline for the coconut.

He is.

Come on, you can do it.

Look at him. He's...he's hanging

almost backwards up the pole,

like an acrobat - I love it.

To get their claws on what they want,

coconut crabs have become

nimble climbers, too.

Oh, my goodness.

Here he goes.

He's not gonna drop it.

Look at how he hangs on.

- He didn't drop it. - Perfection.

I can't believe he just did that.

- That's amazing. - They're real survivors.

Here on Christmas Island, you know, they're...they're the kingpins.

They rule the place.

For robber crabs to evolve such an astounding set of skills

is quite remarkable.

It's what's earned them their name

and the reputation as the island's resident kleptomaniacs.

A highly developed sense of smell,

great strength and dexterity,

combined with intense curiosity,

has led to what could be described

as a blatant disregard for personal property.

And, yet, these traits are exactly what make the coconut crab

so successful out here.

But it's not just these crabs

who turn to crime to find food.

Around the world, animal thieves are wreaking havoc.

Breaking and entering.

Shoplifting.

And even mugging.

For some animals,

stealing has become a way of life.

Frigate birds can get up to 40% of their food

by carrying out mid-air shakedowns on their neighbours.

And this gang of baboons thrive on the spoils

from the steady stream of people at a border crossing in Zimbabwe.

In fact, when food is hard to come by,

finding new ways to get what you need can be essential for survival.

The dizzying heights of the Rocky Mountains.

Home to an incorrigible crook...

..the pika -

a rather adorable relative of the rabbit.

It's August and summer is in full bloom.

(SHRIEKS)

But the days of plenty won't be here for long.

These slopes are only free from snow for 10 weeks a year

When winter comes, this pika will be trapped in its burrow.

To survive,

it needs to stock up the larder.

But while home is up here,

the food is all the way down there.

Every summer, pika must collect enough plants

to see them through the tough times to come.

Multiple trips are inevitable.

And anyone living high up on the slopes,

like this female,

has their work cut out for them.

She may make over 10,000 trips in just one season.

And the grand result

of this frenetic activity...

..is a haystack.

These stockpiles of food

can weigh up to 28 kilograms.

That's more than 180 times a pika's own body weight.

It's exhausting work.

Perhaps there's another way.

An easier way.

Just down the slope,

another pika is getting started

on his haystack,

But he's being watched.

It's daylight robbery.

But this is not just reckless behaviour.

By taking food that's so much closer to home,

our pika is saving precious time and energy.

It's so tempting,

she may well become a repeat offender.

But it's a risky business.

(SHRIEKING)

Caught red-handed.

Every bandit needs a good getaway route.

And it's worked.

But unfortunately,

she's not the only thief on the mountain.

Time to get back to work.

Being skilled enough to successfully steal food

can mean the difference between life and death.

And one animal has become particularly renowned

for its light-fingered ways.

After humans, rhesus macaques

are the most widespread primates on our planet.

Across mainland Asia, they thrive in urban environments...

..where mouth-watering market food is a constant temptation.

These macaques time their robberies perfectly,

using the element of surprise

and making a swift exit.

But what's the secret to their expert thievery?

It's all down to the decisions they make

before carrying out the crime.

If I was going to try and nick this plate of cookies,

my first thought would most likely be about

avoiding getting caught.

It might seem obvious,

but being able to think about the consequences

of being seen by someone

and what their intentions might be

is a complex task for the brain to perform.

In fact, it was once thought to be a uniquely human capacity.

But science is changing all that.

I'm meeting Laurie Santos,

who has studied this troupe of rhesus macaques for over a decade.

Based on her experience of these pilfering primates,

she's devised a test to find out what makes them so good at stealing.

We have been duped by monkeys on this island a lot.

Every time we place our lunch down

and stop paying attention for something,

we look back and we realise it's gone.

They must be cueing in to what we can see and what we can't.

Otherwise, they wouldn't be such great thieves.

So, Laurie, how exactly is this test going to play out?

What we're going to do is try to see if we can find a monkey

- who's interested in stealing from us. - OK.

We're going to use some really delicious grapes,

and I and one of my research assistants

are going to approach monkeys with these grapes.

We're gonna put it on a little foam platform

and place it on the ground,

and one of us is going to turn around.

And the question is, does the monkey understand

that the best person to steal from is the person who can't see?

For the test to work, we need to get

one macaque's undivided attention.

We're just trying to find some monkey

who's maybe by himself.

There's is a guy over there we might be able to try.

The lure of the grape eventually works on this male.

OK, ready?

- Step. - Here we go.

Show.

Down, up.

One turns around.

I love the way it looks around

to check out who else in the hierarchy is around

that might fight him off.

Which one is it going to go for?

Boom!

Takes the one from the researcher that's turned away.

Our macaque makes a beeline for the unguarded grape.

And this happens in 9 out of 10 tests.

That was really fascinating to watch.

What was going on in that macaque's brain

as he was figuring out which grape to go for.

Yeah, I mean, my guess is the first thing that's going on in his head

is just, like, "Grape, grape!"

I mean, he's...the guy who's out there on that little stretch

is probably a really low-ranking monkey.

He hasn't had a big meal in a while. He wants that grape.

But the neat thing is he doesn't just see the grape and run for it.

He's socially processing.

He's like, "Is it OK for me to take it?"

And the first one, the one where the person's looking,

he pauses and he's like, "I can't.

"This person is really big," you know? "It's probably their grape.

"They're going to stop me if I try to do this."

But the person who's looking away, the monkey's like,

"Hmm, I think...I think the coast is clear for this one."

So this is not just about understanding

where that human's eye gaze is going.

It's...it's more complex than that.

That's exactly right.

What we're showing is that primates are taking into account

what another person sees,

and what that person knows

before they make these decisions.

This research shows that rhesus macaques

are clever enough to imagine

what the individual they're stealing from might be thinking -

what's known as theory of mind.

When you live in a large group

of intelligent animals,

being able to watch and interpret another's behaviour can be crucial.

And if you can learn how to target the right monkey to steal from,

it pays off.

So, what we perceive as naughty behaviour -

the ability for macaques

to basically steal everything and anything, given the chance -

is, in fact, testament to just how intelligent these macaques are.

Yeah, they're using their understanding

of this person's different perspective

to steal really effectively.

Laurie believes that theory of mind in primates

may have evolved in order for them to cheat, deceive

and steal from each other.

And this ability can give them the upper hand with us, too...

..allowing them to take advantage whenever the coast is clear.

While stealing has proved highly successful for many,

for others, the challenge to find food is so great,

they must turn to even more sophisticated strategies.

When you're a predator,

you have to actively seek out and catch your prey.

But the game between the hunter and the hunted is never easy.

From evasive manoeuvres...

..to chemical weapons...

..and frightening displays...

..animals everywhere have developed incredible ways to avoid being eaten.

And that's driven predators to evolve

highly sophisticated and even, at times, devious tactics.

Even one of the world's most notorious hunters

has to use every tool at its disposal to get a meal.

The tiger.

And one of its main prey, a chital deer.

These deer have excellent hearing, a finely tuned sense of smell

and are incredibly fleet of foot.

The tiger needs to get close enough to ambush its prey.

Not easy for a 200-kilo cat.

It has to be a master of subterfuge.

Large paws allow the tiger to move almost silently.

Approaching downwind helps it to evade detection.

And its unmistakable stripes conceal its outline

in the shadows of the forest.

But it turns out the tigers are using a far more evasive ploy

to dupe their prey.

And it's all to do with that eye-catching orange coat.

Scientists John Fennell and Laszlo Talas

from Bristol University's Camouflage Lab

are exploring how the tiger's colour

could actually be giving it yet another advantage.

To understand how, I need to see the world through the eyes of a deer,

and this fetching pair of glasses will allow me to do just that.

Most humans have trichromatic vision,

meaning we have three different colour receptors in our retina,

enabling us to see the world in full colour.

But deer are dichromats.

Their colour vision comes from just two colour receptors,

so they can only see greens and blues.

A filter in the glasses blocks any red light from reaching my eyes

to let me see the world like a deer.

Right, John, so how is this going to work?

We're going to show you a series of images

and they all contain a tiger in them somewhere.

All we want you to do is press a key on the keyboard

as soon as you see the tiger.

Right. So, this is all... this is time-dependent.

This is about how quickly I can spot the tiger.

- It is, yes. - OK.

Are they really tricky?

Uh, that's to be seen.

Alright. I'm ready, John.

I'm quite nervous. I think I need more coffee just so I'm sharper.

Okey-dokey.

The big screen fills my field of vision.

What would take me less than a second to spot normally...

What?!

There isn't one in here.

..now become significantly more difficult.

I can't tell whether that's the tiger there at all.

No, it's not.

Ahhh!

Where is it? Where is it?

Where is it? Is this...? Ooh!

It's behind you!

Seeing the world through the eyes of a deer...

Are some of these tricks?

There isn't a tiger here.

..results in the tiger becoming very hard to pick out.

Ooh!

Sometimes when they're closer, they're harder to spot.

Isn't that weird?

If I'm a deer. I'm dead.

That was surprisingly more difficult than...than I imagined.

The tiger was very big and close up, and I missed it on a few occasions.

Yes, you did.

You, overall, were about half the speed you would have been

if you'd not been wearing the dichromat glasses.

So, essentially, what this is saying is that if a deer was trichromatic,

it could spot tigers twice as fast.

Twice as quickly as you did.

That would be the difference between a kill and not a kill,

if you're a tiger.

Through our eyes, the tiger looks like this.

But through the eyes of a deer, it looks very different.

The colour orange now blends into the background.

This new research reveals

that tigers are able to get up to seven metres closer to the deer

without being spotted.

And that can make all the difference.

So, why are tigers not just green, then?

For tigers to be green would require

a very big difference in their physiology, their biochemistry.

- There are no green mammals. - There are no green mammals. No.

And, obviously, it's not necessary 'cause orange looks green anyway.

It doesn't need to go green.

It doesn't need to go green because to the deer, to the prey...

- It's green. - ..it is green.

The stunning orange coat of the tiger

acts as an excellent visual deception -

yet another perfectly honed capability

that makes this predator the king of the forest.

We've been studying tigers for decades

and, yet, one of the most fundamental and obvious questions

about their camouflage

is only beginning to be properly addressed.

It's what their prey perceives that counts,

and that's driven the evolution of

a highly effective means of concealment.

But, of course, tigers are not the only predators

to have evolved formidable adaptations

in order to stay one step ahead of their prey.

The panther chameleon of Madagascar.

It harbours a concealed weapon

that packs a powerful punch.

Its tongue shoots out at a speed of up to five metres a second -

so fast its prey rarely see it coming.

In Australia's Great Barrier Reef,

this cone snail is one cunning mollusc.

The fish it hunts are fast.

So, it waits until they're asleep.

Sneaking up, it releases an invisible chemical weapon.

Once paralysed, the fish are eaten alive.

But perhaps one of the ocean's most aggressive predators

is the thresher shark.

Whipping its tail at speeds of up to 50 miles an hour,

it beats its fish before it eats them.

Being armed and dangerous is a sure-fire way to catch prey.

But other predators face a very different problem.

What do you do if your prey can kill you?

The tropical rainforests of Queensland.

Home to a hunter who's diminutive but deadly.

The jumping spider.

Rather than spinning a web,

this predator uses stealth to catch its prey.

But the food it most desires

seems out of reach.

An ants' nest, full of delicious larvae.

The problem is they're guarded

by a vicious army of adults.

These green tree ants dominate the treetops.

Each colony can contain as many as half a million workers.

They use a chemical signal or code

to identify each other.

At the first sign of an intruder who smells unfamiliar,

they're hard-wired to retaliate with violence.

Armed with formidable jaws,

the ants could kill our jumping spider with ease.

Getting hold of the ant larvae seems like an impossible mission.

But these spiders

have evolved some remarkable tricks

to get to much-needed food sources.

In fact, it's thought that about 300 species of spiders

can mimic ants -

a particularly cunning capability

known as myrmecomorphy.

Predators all over the world

use the element of disguise to dupe their food.

By pretending to be a harmless branch,

this African vine snake tricks its prey into thinking they're safe...

..when they could be about to get eaten.

In Hawaii, a fly is in for a shock...

..from a carnivorous caterpillar in a leafy costume.

And while it may look just like an alluring flower,

this orchid mantis is a stealthy assassin.

But compared to these exceptional masquerades,

our spider's disguise is... well, a little rubbish.

Its colour is a good match.

It has a decidedly un-spider-like nip

at the waist,

just like an ant.

But surely, no-one

would mistake one for the other.

Nevertheless, it heads for the nest.

Will it get away with it?

Mission accomplished,

and right under the ants' radar.

But it wasn't its appearance that did the trick.

It's mastered a far more complex impersonation.

Our spider carries with it the ants' chemical code.

Like all of its kind,

it was born in a green ant nest.

Its mother laid her eggs there.

It fed on ant larvae from birth

and developed the ability

to smell just like them.

Now that it's essentially hacked into their security,

it can rob the nest whenever it likes.

Using a chemical disguise,

a spider can help itself to a meal

without getting attacked by its very aggressive prey.

That's incredibly impressive

for a creature most of us wouldn't give a second thought to.

I love it.

Tricking prey is ingenious behaviour.

It takes creativity to get the food you need.

Some animals will even work with another species to do it.

These arrangements should be mutually beneficial.

One species gets the food...

..and the other gets a service in return.

But while it works well for the agama lizard and the lion...

..the hunger game can be more ruthless.

This pygmy falcon

is about to become a father.

Like all parents,

he and his mate need to provide

for their new arrivals.

While he's just 20 centimetres tall, the size of a budgie...

..this bird of prey is a skilful hunter.

But his next concern is to provide a home for the family.

And nest-building is not his forte.

Fortunately, here in the southern Kalahari,

our pygmy falcons have some master nest-builders on their doorstep.

A colony of insect-eating social weavers.

And this is where they live.

A highly sought-after property

of 100 individual homes,

The biggest avian construction in the world.

Expertly maintained by the skilful weavers.

It's the perfect residence...

..for our falcons.

So, they've moved in,

kicking out the current occupants in the process

For the weavers, this is a disaster.

Not only have one pair lost their home -

now the others have a predator living on their doorstep.

But the falcons are not quite the villainous neighbours

they might seem.

They make the weavers an offer they simply can't refuse.

Protection.

These nests are regularly plagued

by unwelcome visitors...

..like mongoose...

..and hungry cobras.

Cue security.

The weavers' residence now has its own live-in protection.

It seems like a good arrangement,

but the pygmy falcon is a predator.

It's not long before the weavers and falcons

all have new mouths to feed.

The new falcon chicks need to eat

nearly half their body weight in food daily.

And as the dry season reaches its peak,

the adults have to work harder to find enough to feed them.

What they need is something easy.

Something close to home.

A weaver chick.

To eat the chicks the falcons are supposed to be protecting

seems like a shocking betrayal.

But the falcons must tread a fine line.

If they take too many chicks,

the weavers might desert the colony...

..leaving a huge, vacant home, with no food.

But this pair of falcons have played it just right.

The falcons have fledged two chicks.

And despite their losses,

the weavers are thriving, too.

By providing protection, whilst not being too greedy,

the pygmy falcons have found a perfect short cut

to feeding their family.

While the pygmy falcon at least give something back in return,

on the opposite side of the world,

another bird has found a way

to violate one of the most longstanding arrangements

on the planet.

The cloud forests of Ecuador.

Home to over 130 different species

of hummingbird...

..including the wedge-bill.

But behind these enchanting looks

lies one of the most criminal behaviours in the rainforest.

To get its food, this little bird

does something truly outrageous.

Hummingbirds are, quite simply, mesmerising creatures,

capable of spectacular feats

of aerobatics.

Their wings can beat

up to 80 times per second,

allowing them to break and turn

and hover in mid-air.

But this impressive ability does come at a price.

It needs to be fuelled

by high-energy food, and lots of it.

The diminutive hummingbird

is, in fact, a very big eater.

Our wedge-bill and all other hummingbirds

have to eat more than twice their body weight in food each day.

They burn through calories so quickly

that if they were the size of an average human,

they'd need two cans of fizzy drink every minute to survive.

But over millions of years of evolution,

they've struck up a bargain with the surrounding plants

to get what they need.

The plants produce flowers rich in nectar.

In exchange, the hummingbirds act as pollinators.

Moving pollen between flowers,

they enable the plants to reproduce.

But each flower only has a limited supply of nectar each day,

which means the hummingbirds must compete for it.

Each species has a unique ploy

to get their prize.

The green violetear is one pugnacious little bird.

Engaging in aerial combat,

it prevents all others

from getting close to its patch.

Th booted racket-tail takes a different approach...

..using agility and speed

to outmanoeuvre the opposition.

And the tiny, purple-throated woodstar

has a very clever trick.

Most hummingbirds are terrified of bees.

Just one sting could be fatal.

So, the wood star mimics the sound of a bee with its wings,

scaring other hummingbirds off

just long enough to get the goods.

Whilst these birds may be somewhat brazen in their approach,

they hold up their end of the bargain with the flowers.

Our wedge-bill, however, has a far more rebellious plan.

While the other hummingbirds fight it out, it makes its move.

The wedge-bill doesn't reach inside the flower.

It goes straight to the base

and pierces a hole where the nectar is stored...

..tapping into the very source.

It gets the food it needs,

but it doesn't pollinate the plant.

Our resourceful little wedge-bill

has found a quick and effective way

to get nectar from flowers.

But if pollination isn't taking place,

effectively, it's robbing the nectar

without carrying out its part of the bargain -

something that scientists call 'floral larceny'.

By reneging on its deal with the plants,

the wedge-bill has outwitted the competition

and found an easy way to access any nectar it chooses.

Getting its fill of the bounty without returning a favour

is cheating,

but finding a novel way to forage

gives our wedge-bill a chance to thrive in a very competitive world,

and that just makes me admire hummingbirds all the more.

Animals will steal, trick and cheat their way to a meal.

But sometimes, to get the food they need,

brute force may be the only answer.

With over 150 individuals,

this is one of the largest communities of chimps ever recorded.

So, there's a huge pressure to find food.

Chimp family groups need to secure

as many resources as possible,

so they're always on the lookout for new opportunities.

Taking the lead from the alpha male, they can carry out daring raids

in their rivals' territory.

But the question is, is it a risk worth taking?

The prize in this case is a fig tree full of fruit.

But there's another group already in it.

A patrol sets out into the forest.

The chimps move with purpose...

..and in silence.

Signs of the rival group confirm they're nearby.

It takes an extraordinary amount of skill to get so close

without being detected,

but that's only the first part of this fascinating behaviour.

So many chimps gathered together like this

represents a lot of muscle power,

capable of carrying out a full-on attack.

The patrol edge forward.

The way in which the chimps approach is so deliberate, so coordinated,

that some scientists liken it to an act of warfare.

(SHRIEKING)

Loud calls announce the start of the battle.

The aim is to terrorise and intimidate their rivals.

This is a numbers game,

and they need to show they're a formidable group.

They push out the opposition.

In such a frenzied situation,

it's all too easy to become a victim.

(SHRIEKING CONTINUES)

One female is brutally attacked.

She escapes, but chimps can easily be killed in fights like these.

Resorting to violence has worked.

And now they can feast on the best fig tree in the area.

To get the resources they desperately need for the group,

chimps must try to expand their territory

by any means possible.

Mounting an all-out attack is a massive risk.

But if it means all the family get to eat, it's a risk worth taking.

Food is essential to survival,

and it can be hard to come by.

So, it's no wonder it's resulted in so many...

(SCREECHES)

..seemingly underhand tactics.

From theft...

..to predatory tricks...

..broken promises,

and even brute force.

The lengths animals will go to to get a meal are simply spectacular.

Finding food is a fundamental need,

and it's driven the evolution of some extraordinary survival strategies

all across the animal kingdom.

Look at that!

Now, some species will clearly stop at nothing,

but what can be mistaken as dishonest behaviours

are, in fact, remarkable approaches

to winning the source of food that's up for grabs.

And when you look at it that way,

these behaviours are testament

to the intelligence and the resourcefulness

of the animals all around us.

Next time I meet nature survivors -

the delinquents..

They're breaking and entering.

..deceivers...

..and brutes,

doing whatever it takes to stay alive.
