Frigate birds display and
exchange nesting material

Waved albatross dance

The need to lay their egg on firm ground
ties the albatross to the coast

but parental responsibilities
are shared

While one looks after the egg,
...the other can go off to feed

The need to breed brings
many different animals

to the coast each year
for a few weeks

Male sea turtles spend all
their lives at sea, but the females,

like birds, must come to
land to lay their eggs

To do that green turtles that live
and feed off the coast of Brazil

swim fifteen hundred miles to the
tiny island of Ascension

that lies bang in the middle
of the Atlantic Ocean

Exactly how they manage to
navigate with such accuracy

and find this tiny lump of rock,
just seven miles wide is a mystery

But each year up to five thousand
turtles manage to do so and then,

close to the coast of Ascension,
they mate

Travelling to and from Ascension and
nesting here can take up to six months

and throughout that entire time,
none of them feed at all

After mating a female has to
leave her natural element

and haul herself up onto land

She does so at night,
laying about three or four times

at around fifteen day intervals

After that she then swims all the way
back to the seas off Brazil

She returns to this very same
island throughout her life

Remarkably, all the world's sea turtles
return year after year

to just a few traditional
breeding sites

Crab lsland, in Australia,
is one of them

This tiny two-mile long crescent of sand,

lying a few miles off
Queensland's northerly tip,

provides nesting sites
for half the entire population

of one of the world's
rarest sea turtles

Flat-backed turtles are large,
over a metre long

- but they have to be careful

There are other giant
reptiles here too

Salt-water crocodiles

Every night throughout the year

there are flat-backs burying their eggs
all along this lonely stretch of sand

Nine weeks later and things
are about to happen

These eyes shining in the darkness
belong to night herons

As if from nowhere, hundreds of birds
suddenly appear on the sand dunes

Pelicans wait patiently

Jabiru storks pace up and down

Before long they see what
they've been waiting for.

Because these turtles lay
their eggs throughout the year,

the hatchlings emerge night after night
in a steady trickle of beak sized meals

Pelican's broad beaks allow
them to dig out the hatchlings
