About These Birds

Black-crowned Night Heron

The Black-crowned Night Heron is a stocky, medium-sized heron with a distinctive black crown and back, grey wings, and white underparts, found on every continent except Australia and Antarctica. It inhabits a wide range of wetlands including marshes, swamps, rivers, and coastal areas, feeding nocturnally on fish, frogs, invertebrates, and small mammals. It nests colonially in trees or shrubs near water.

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.
