Bare-throated Tiger-heron

The throat is bare and is greenish-yellow to orange in all plumages. The adult has black crown and light grey sides of head, the sides of the neck and the upperparts otherwise blackish narrowly barred buff. The median stripe down the foreneck is white bordered with black; the remaining underparts are dull cinnamon brown. The juvenile is buff coarsely barred with black, more mottled and vermiculated on wings; the throat, median underparts and belly are whitish. The flight is heavy, and the call is a hoarse howk-howk-howk. Males also give a booming hrrrowwr! call, especially at sunset. During emission of the call, the beak opens wide and undulations can be seen along the course of the throat from mid-thorax caudally.
