A tiny, bright green parrot with an orange bill, a slim red throat patch, and a red tail. Juveniles have a yellow bill and lack the throat patch. Inhabits the canopy of lowland and hill forest, where usually encountered singly, sometimes in company with Sulawesi Hanging-Parrot. Differs from that species in its smaller size, red bill, green forehead, and uniform green mantle. Calls include a very high-pitched, insect-like “sit,” sometimes given in rapid couplets, that can be hard to hear.
