Owl parrot / Kakapo (Strigops habroptilus). Field Museum of Natural History, Chicago. Conservation status: critically endangered. The kakapo is the only flightless parrot in the world. It is also the largest parrot. The first human settlers of New Zealand were the Maori. They hunted kakapo for feathers and meat. The Polynesian dog and rat introduced by the Maori caused a further decline. When Europeans settled in the 1800s, the situation became critical due to deforestation and hunting. The kakapo is particularly vulnerable to predation by mammals due to its strong scent, habit of freezing when threatened, its ground nesting behaviour and flightlessness.
