Medium-sized, stocky rainforest parrot. Can appear mostly black even at fairly close range. Tends to occur as single birds or pairs rather than large groups. Flight style distinctive; birds appear to keep wings below the horizontal, rolling from side to side. Usually first detected flying overhead; descends rapidly and silently into forests to feed on fruit and flowers in the canopy. In flight, confusion is possible with Blue-headed Parrot, but Dusky has different flight style with shallower wingbeats and different calls.
