Kiwi Bird

Kiwi bird is a flightless, solitary, nocturnal bird found just in New Zealand. Three living species, all in the genus Apteryx, comprise the family Apterygidae. They are usually classified in their own order, Apterygiformes. Named for their cry, kiwis are brownish or grayish in color and may be streaked or barred. They have small heads, hairlike plumage, minute wings, and no external tail. The bill is long and slender, with nostrils near the tip.

Kiwis range from 1.25 to 4 kg (2.75 to 9.0 lb) in weight and from 45 to 84 cm (18 to 33 in) in length and stand up to 30 cm (1 ft) high. They inhabit humid forests or swamps, where they feed on insects, snails, barries, and especially earthworms. Recent experiments confirm that kiwis locate food by smell, which is unusual for birds. The one or two very large eggs, each about 13 cm (5 in) in length and 400 g (14 oz) in weight, are laid in a burrow, and the smaller male incubates them for about 11 weeks. The little spotted kiwi, A. oweni, seems to be disappearing.

Prior to the arrival of humans in the 13th century or earlier, New Zealand's only endemic mammals were three species of bat, and the ecological niches that in other parts of the world were filled by creatures as diverse as horses, wolves and mice were taken up by birds (and, to a lesser extent, reptiles). Beside the name of animals kiwi also name of fruit, kiwi fruit, this fruit can grow in china, New Zealand and California.
