About These Birds
Black-headed Heron
The Black-headed Heron is a large, stately heron with a black crown and hindneck, gray body plumage, and a contrasting white throat and foreneck. It is widespread across sub-Saharan Africa, inhabiting grasslands, marshes, cultivated land, and open country—often far from water compared to other herons. It feeds on insects, frogs, rodents, and small birds, standing motionless or stalking prey on foot.
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.
