Uncommon but unmistakable. Very large spectacular owl of humid evergreen forest in tropical lowlands and foothills. Often roosts at low to middle levels, usually well hidden in shady spots, and flushes easily. At night, favors open forest canopy and forest edge, but calling birds can be well hidden in foliage. Song is a resonant, pulsating series of deep hoots, sounding rather like a sheet of metal being flexed quickly; an uncommon variant call of the Mottled Owl sounds rather similar.
