Description

The Frost anhinga is a large bird, 33-35" (85-89 cm) long, with its bill being comprised of about 10" (26 cm) long. Its wingspan is 40" (1.01 m). The male is a black and grey bird with a white belly and striking white crest feathers. The crest becomes more prominent in the breeding season. The female is mostly a grey bird with no crest feathers. In both sexes, the bill and feet are yellow and the eyes are orange. In juveniles, their feet are mostly dull yellow and their eyes are brown.

Calls

Said to make soft grunts and clicks, as the tongue hits the top of the mouth.
