Fairly large, black parrot that is found in and around all types of forest. Often seen in flight, sometimes in small, loose flocks. Incredibly loud calls consist mainly of musical whistles. Can be very hard to separate from Greater Vasa Parrot, but smaller and smaller-billed, with a curving edge to the skin at the back of the bill. Vocalizations are higher-pitched and more musical than those of Greater Vasa Parrot. Can easily be mistaken for a raptor in flight, but has all-black plumage unlike any raptor in range.
