Kiwis Breed More Kiwis

New Zealanders were called "Kiwis" in the WWII after their national bird. Such a strange little bird too: flightless, nocturnal, and a recluse living in dense rainforest. But New Zealanders have put a mighty effort into breeding the bird to replace declining numbers in the wild due to habitat loss and introduced predators. This year has produced a bumper crop of kiwis, 14, at the Pukaha-Mount Bruce wildlife refuge. This breeding season was the most successful since 2003. Caretakers were rewarded with an extra surprise, a rare all white kiwi chick, thought to be the first raised in captivity [photo]. Maori tribal elders see the chick as a 'tohu' or sign of new beginnings. Named "Manakura" it will be released to the 940 hectare native forest refuge when it reaches suitable weight. The chick is not albino, but the progeny of a race of kiwis from Little Barrier Island that have white markings. The chick's all white feathers may be an evolutionary disadvantage since it will standout midst the dark of the forest floor.
