About These Birds
Southern Brown Kiwi
A robust flightless kiwi with coarse grey-brown hair-like feathers and a long decurved bill. Strictly nocturnal and largely solitary, probing leaf litter for earthworms, insects, and berries. Confined to South Island and Stewart Island of New Zealand. Lays the largest egg relative to body size of any bird.
Little Spotted Kiwi
The smallest kiwi weighing around 1 kg, with pale grey plumage finely barred with brown. Nocturnal and insectivorous. Now survives mainly on predator-free Kapiti Island after mainland extinction from introduced predators. Population recovering under intensive management.
