Born in the forest,
they stay in the forest,
while Mum and Dad bring fresh meals straight from the ocean.
They can hear the waves,
they can even smell the spray,
but they have no idea what it looks like.
These chicks won't have their first splash in the ocean
until they're three months old,
when they'll finally set off on their first fishing trip, alone.
1,500 miles from the nearest continent,
New Zealand is beyond the reach of most mammals.
Marine mammals aside,
the only ones that did succeed,
before humans arrived, had wings.
Bats.
This is the short-tailed bat.
It roosts in tree cavities and comes out at night to feed.
So far, so normal.
But these bats have been living the island life
far too long not to have become a little ''different''.
And they're not the only ones.
Wetas are primitive relatives of the locust,
but they can't fly.
