National Geographic: Last Feast of the Crocodiles

---

This is the story of a pool and the

animals that cannot live without it.

It's a place where hippos

and crocodiles survive

in mysterious harmony.

A crowded pool...

where predator and prey

are drawn together

and where strange things happen

that have rarely been seen before.

At this pool thirst can be dangerous,

and drinking...

becomes a deadly game of chance.

When the pool shrinks in

an unrelenting drought...

there is a desperate fight for life.

A wild anarchy takes over that

only the fittest can survive.

Here in a strange communion hippos

attend the last feast of the crocodiles.

A river in Africa...

It's known as the Luvuvhu

or Hippo river,

and where land and river meet there

exists a rich concentration of animals.

For countless years,

this river has sustained life

in the northern reaches of

South Africa's Kruger National Park.

When good rains have fallen

there is abundant water for all,

but this year little rain fell,

the river dwindled to a narrow channel,

and finally stopped flowing.

The pools that remain in the

river-bed are life sustain oases,

and this which is one of

the largest and deepest,

and has never been known to go dry,

is a favorite refuge

for hippos and crocodiles.

For those who have to

drink here each day

the challenge is

to drink and survive.

With over 60 crocodiles congregated

here caution becomes the first rule.

Wise in the ways of the pool,

oxpeckers, on their floating islands,

drink safely,

and these unpredictable giants

don't seem to mind the few extra

ounces of their company.

But, more extraordinary is this young

crocodile, the smallest in the pool,

who's become a regular passenger

and is possibly safer

basking on the surprisingly tolerant

hippos than with its own kind.

Wily baboons have another strategy.

They dig pits at the pool's edge

and drink the seepage water,

rather than risk a croc attack.

In contrast, this female impala is so

stressed by thirst she's beyond caution.

Dazed and distracted she finally drinks

in the worst possibly place.

Crocs aren't the only problem here.

These impala have run afoul

of a white- crowned plover,

whose eggs are

in a depression in the sand.

These birds only rest nest near water,

and so, when the river dries,

the fringe of the pool

becomes prime real estate.

But it's also a busy

and dangerous throughfare -

crocs come here regularly to bask.

Crocodiles lumbering up the bank are

a major hazard for the fragile eggs.

But, unlike the timid impala,

the crocs ignore the birds' warning cries.

Lucky this time...

and she settles down again to brood.

Hippos spend their nights grazing,

often far from the pool, and,

by day, they too like to lie

in the warm sun.

A large wet snout,

applied with surprisingly gentleness,

seems all that's needed to clear

some space on the crowded beach.

There's no hurry...

we're all relaxed and easy here,

and the great reptiles gradually

respond to gentle nudges

until all accommodated

to their liking.

Another close call for the plovers.

As the crocodile returns to the pool.

But it's all just part of the price

for a good waterfront site.

Hippos are a nuisance for the plovers

- they don't leave much space

between them.

The rains that usually revive

the river are late this year

and the water level in the pool

drops rapidly.

Fishing birds move on

and find good pickings

among the fish trapped

on the shallows.

The yellow-billed stork's

juggling act is no game,

but a way to tire the fish into

relaxing its sharp, erected spines.

Crocs eat fish too...

they're also cunning thieves...

who deliberately harass the birds

into dropping their fish.

The herons must wet their catch

before they can swallow it,

and the crocs watch closely,

waiting to move on and panic

the bird at just the right moment.

Sometimes these waterbirds appear

to live a charmed life

and to be mysteriously immune

from attack by crocodiles.

But birds and reptile

understand each other well.

And the crocs seem to know these birds

are just too alert to be easily caught.

But not all birds are crocodile smart.

Green pigeons don't often drink.

Usually they get enough moisture

from the fruits they eat.

But in the heat of this dry year

the birds are forced to come to water.

And they're innocent of any danger.

The sight of crocodiles spinning

in a feeding frenzy

is enough to frighten

most animals away.

But as the crocs tear apart an nyala

bull, something amazing happens.

A hippo moves on and begins to mouth

and lick the bodies

of the feeding crocs.

Hippos are strictly vegetarians.

She hasn't come for

a share of the spoils.

Why she intrudes

in this way is a mystery.

She is more powerful than the crocs

and her dominance over them

is absolute.

She prods and licks the face of

the biggest croc on the pool -

even as it struggles to swallow

the skull of the antelope.

And then, as if her curiosity

has been satisfied,

she loses interest

and leaves the crocs to their feast.

Elephants don't have to worry about

crocodiles when they drink,

but they still prefer the cleaner water

in the pits and vigorously dig them out.

In the riverbank, near the pool,

a large colony of nesting bee-eaters

are feeding their young.

They must forage continually

in the hot sun to satisfy their needs.

To cool off, every afternoon,

they fly over the pool

and dive for their drinks.

For some of the crocs this is

the signal to take up positions.

The odds are heavily in favor of

the bee-eaters

and most survive the croc strikes.

A thirsty lioness comes to water.

She tries a pit

but finds it full of bees.

She decides to risk the pool.

In heat like this the bees

need water, too.

Lions can go without water

for a long time...

But this one is a nursing mother.

She must drink.

Maybe the bee-pit

isn't so bad after all.

Large flocks of queleas are in the

area, searching for seed and grain.

As they stop by the pool to drink,

their busy fluttering

at the water's edge

inspires the crocodiles with a keen

and almost sporting enthusiasm.

The monitor lizard is the scourge of

both ground nesting birds

and the egg lying crocodiles.

It's a voracious predator,

particularly partial to eggs...

And the feisty plover

immediately declares war.

During the heat of the day

the sand becomes unbearably hot

and burns the skin

between the impalas' hooves.

For the plovers on their nest, this

is when easy access to water pays off.

The bird is soaking its breast-feathers

until they are weighted with water.

It then hurries up the scorching sand

to reliever its mate.

The plovers are brooding on sand

that feels hot enough to fry an egg,

and by mid-day they are changing guard

at the nest every ten minutes.

Without the constant protection

of their cool wet feathers,

the eggs could not survive the heat.

The sand is so hot...

it's a wonder she doesn't fly down.

These buffalo have just

one thing in mind.
