Rotscheitelreiher Gorsachius goisagi

A small brown heron with awkward-looking, hunched appearance. Occurs in dense, damp lowland and foothill forests next to bodies of water, where it hunts prey in dense cover. Paler crown and weaker crest than similar Malayan Night-Heron and lacks the white wingtips of that species. Shy and difficult to see; most readily observed during migration, when it sometimes visits more open habitats. Gives hooting calls at regular intervals, especially in early evening.
