This is a monotypic species[1].


They inhabit a wide variety of forests, forest edges, second-growth woodlands, gardens, scrub and suburbs. Most common in lowlands below 700 meters but have been recorded up to 1800 meters.


Rather shy, they often burst forth with shrill cries when disturbed. They have a firm, jerky flight with shallow wingbeats.


Fruit, seeds, blossoms, leaf buds, epiphytes, large caterpillars and soft-bodied insects. Sometimes raids native gardens for papayas and yams.


Its breeding biology was unknown until 1997 when several nests with young in high natural tree cavities were described[7]. Clutch is usually two or three white eggs.


Common flight call is a quick succession of two or three short grating notes. Also series of double cries with the first note is accented and the second inflected downward.


Presumed largely resident. Occurs mainly in pairs or groups of 5–10 individuals.
