About These Birds

Boat-billed Heron

The Boat-billed Heron (Cochlearius cochlearius) is one of the most morphologically distinctive members of the family Ardeidae, so unusual in appearance that it was formerly placed in its own monotypic family, Cochleariidae. The feature that immediately sets this species apart is its extraordinarily broad, flat, scoop-shaped bill, which is wider than it is long and resembles an upturned boat hull — a structure unlike any other heron bill. Adults have a black cap and crest, pale gray to white breast …

Ascension Night-heron

The Ascension Night-heron was a flightless heron known from subfossil remains on Ascension Island in the South Atlantic. Weighing an estimated 624g, it was likely driven to extinction by human activity and introduced predators. It is currently listed as Not Evaluated by conservation assessments.
