gulnebbsvømmerikse Heliopais personatus

A bizarre bird that loosely resembles a cormorant with a hornbill’s brightly-colored beak. Gray-brown overall with a black mask extending from the face down to the throat that is darker and more extensive in males. A reclusive species, typically encountered at dawn or dusk, skulking in well-vegetated waterways such as mangroves, swamps, and shaded rivers. Gives a loud odd bubbling call followed by an amphibian-like series of clucks.
