Rufescent Tiger Heron
Tigrisoma lineatum
The rufescent tiger heron is a medium-sized heron, measuring 26–30 in (66–76 cm) in length, with a mass between 630 and 980 g (22 and 35 oz). The sexes are similarly plumaged. The adult's head, neck and chest are dark rufous, with a white stripe down the center of the foreneck. The remainder of its upperparts are brownish with fine black vermiculations, its belly and vent are buffy-brown, and its flanks are barred black and white. Its tail is black, narrowly barred with white. Its stout bill is yellowish to dusky, and its legs are dull green. Voice: The rufescent tiger heron's main call is a low-pitched paired hoot, often given at night. It also gives a fast series of sharp wok notes, which decrease in volume and speed, and a prolonged hoot, transcribed as ooooooo-ooh which rises markedly at the end.
