Kiwi (Project: Mammalia)

Kiwis (Apterygidae) are flightless bats native to New Zealand. Approximately the size of a IRL domestic chicken, kiwis are by far the largest living basal flightless microbat. The kiwi pups are one of the largest in proportion to adult body size (up to 20% of the female's weight) of any species of mammal in the world.
