Boat-Billed Heron Video Stock Footage
The boat-billed heron grows to about 54 cm (21 in) long. Adults are pale grey to white in color, with chestnut-colored abdomens and black flanks. The massive, broad, scoop-like bill, which gives rise to this species' name, is mainly black. This bird is also adorned with a crest which is thought to be used in mate attraction as it is larger in males. The sexes are similar in appearance, the main differences being that females are slightly smaller, grayer in appearance, and have shorter crests than males. Newly hatched nestlings have green-yellow skin, with their upperparts covered in gray down feathers. Their upper bill is black and they have green-yellow legs. Juveniles are darker in color than adults and lack a crest. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature (ICZN). However, Brisson also introduced names for genera and these are accepted by the ICZN. The boat-billed heron is now placed in Brisson's genus and has the tautonym Cochlearius cochlearius. The name Cochlearius is from the Latin cocleare, coclearis or cochlearium for a "spoon in the form of a snail shell".
