About These Birds

Black Bittern

The Black Bittern is a medium-sized, slender heron of South and Southeast Asia and Australia, with males displaying largely black upperparts, a tawny-yellow neck, and streaked underparts. It inhabits densely vegetated wetlands, including reed beds, mangroves, and overgrown ponds and streams. It is secretive and crepuscular, feeding on fish, frogs, and aquatic invertebrates.

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.
