Alpine parrots, called ''kea'', after their calls.
Living higher than any other parrots,
these are possibly the world's most playful birds.
But most of New Zealand's pioneering creatures were drawn to the forests below.
And here, too, given the strange nature of life on Pacific islands,
it pays to expect the unexpected.
And the last thing you might expect to see here is penguins.
These are Fiordland crested penguins, named after this corner of south New Zealand,
They're on their daily trip to the sea.
Despite hanging out in the forest, they haven't lost their taste for fish.
So why are these woodlands so attractive to penguins?
Because there are no large predators here,
it's a safe place for bringing up baby.
A freshwater stream through the forest makes a handy highway for a parent penguin heading home from a fishing trip with a crop full of food.
