It is endemic to forest in the Bismarck Archipelago in Papua New Guinea.

Both sexes feature a mainly green body with a bright red patch on its throat, a black beak, and yellow eyes.

Females feature green cheeks (along with males) but, have a slight green/blue wash. Juvenile birds have no throat patches, and have a brown beak and eyes.

Its diet consists of various wild fruits, flowers, buds, and it will sometimes consume small insect larva (for extra protein sustenance).

[1] Like many other birds in the Bismarck Archipelago, the Bismarck hanging parrot is threatened by deforestation, encroaching human settlement, mining operations, and illegal logging.
