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.
