Ribbon Tailed Astrapia
The ribbon tailed astrapia has the largest tail-length-to-body ratio of any bird. The bird's body is usually about one foot long, while the tail feathers are three feet long. Its body looks a bit like the body of a peacock. The long tail is only found in the male bird.
This is the world's longest flying bird — about three feet from beak to tail. It's so huge that it eats monkeys.
The flightless kiwi is part of the family that includes ostriches and emus, despite the fact that it's only the size of a chicken. The kiwi has the largest egg to body size ratio of any bird — it lays an egg that is roughly 6 times the size of a chicken egg. A male and female kiwi will remain mates for about 20 years, and the male is usually the one who incubates the eggs.
The kakapo is the only flightless parrot in the world, and it's also nocturnal, which is extremely uncommon for parrots. It's critically endangered because of predators introduced to its home (New Zealand), and because it only mates about three times a decade, when the fruit of the rimu tree is abundant.
