The kea ( KEE-ə; Māori: [kɛ.a]; Nestor notabilis) is a species of large parrot in the family Strigopidae that is endemic to the forested and alpine regions of the South Island of New Zealand. About 48 cm (19 in) long, it is mostly olive-green, with brilliant orange under its wings, and has a large, narrow, curved, grey-brown upper beak. Its omnivorous diet consists mainly of roots, leaves, berries, nectar, and insects, but also includes carrion. It was once killed for bounty due to concern by sheep farmers that it attacked livestock, especially sheep. The kea is now uncommon, and received absolute protection under the Wildlife Act in 1986.

The kea nests in burrows or crevices among the roots of trees. Kea are known for their intelligence and curiosity, both vital to their survival in a harsh mountain environment. Kea can solve logical puzzles, such as pushing and pulling things in a certain order to get to food, and will work together to achieve a certain objective. They have been filmed preparing and using tools.

The kea is a large parrot measuring 46 to 50 cm (18 to 20 in) in total length, with some specimens possibly reaching 55 cm (22 in). Adult kea weigh between 750 and 1,000 g (1.65 and 2.20 lb), with males averaging 956 g (2.108 lb) and females averaging 779 g (1.717 lb). One source listed the mean adult weight as 922 g (2.033 lb) It has mostly olive-green plumage with a grey beak having a long, narrow, curved upper beak. The adult has dark-brown irises, and the cere, eyerings, and legs are grey. It has orange feathers on the undersides of its wings. The feathers on the sides of its face are dark olive-brown, the ones on its back and rump are orange-red, and some of the outer wing feathers are dull blue. It has a short, broad, bluish-green tail with a black tip. Feather shafts project at the tip of the tail and the undersides of the inner tail feathers have yellow-orange transverse stripes. The male is about 5% longer than the female, and the male's upper beak is 12–14% longer than the female's. Juveniles generally resemble adults, but have yellow eyerings and cere, an orange-yellow lower beak, and grey-yellow legs.
