About These Birds
Great Blue Heron
The great blue heron is the largest heron in North America, standing up to 1.4 meters tall. These patient hunters can stand motionless for extended periods before striking at prey with remarkable speed. They nest in large colonies called heronries, often returning to the same site year after year.
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.
