📖 1. Overview
The Palm Cockatoo is a large, all-black cockatoo living in the rainforests of New Guinea and northern Australia. Its IUCN status is Near Threatened (NT).
🦴 2. Anatomy & Morphology
It is almost entirely black and can raise and lower a crest about 15 cm long on its crown. Because its bill never closes completely, its black-tipped red tongue is always slightly visible, and males have a larger bill.
🔍 3. Ecology & Behavior
It feeds mainly on leaf buds, seeds, and fruits, occasionally eating insects, and crushes hard seeds and nuts with its powerful bill. Pairs bond for life and breed from August to January; unable to excavate their own cavities, they nest in hollows of large trees such as palms.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
