Habits and Behavior
Nocturnal, resting by day in thick foliage, but occasionally will become active on dark cloudy late afternoons. Its commonest call is a rapid series of six to eight low rattling hoots, bobobobobobo, lacking in resonance but far-carrying, sounding almost like a distant machine gun. Decoys readily to a tape of its voice. Juveniles give a slightly hoarse loud whistle, hweew.
