RUFESCENT TIGER-HERON Tigrisoma lineatum
Tiger-Herons are intermediate between true herons and bitterns - the relation to the latter particularly obvious in the bittern-like juvenile plumage. They are stocky, thick-necked herons, often quite crepuscular in behaviour and freely perch in trees. Nervous birds flick the tail slowly (see Video), before flushing to a low tree giving a croaking call.
