Определение
Small, dark heron with a blue-green back, rusty-colored neck and dark cap. Usually in a crouched position, partly concealed in vegetation, waiting patiently for prey. In flight, looks like an awkward crow with broad wings, neck tucked in, and legs extending just beyond the tail. Often vocal when flushed; gives a sharp "skeiw!"
