 Description 
Table Of Contents: At sunset when most herons are flying toward their roosting places, the black-crowned night herons are leaving the trees where they have spent the day scattering over the marshes to feed. By foraging at night, these birds avoid competition with other herons. Probably the most abundant heron in the world, the black-crown night heron nests on every continent except Austrialia, where its place is taken by a closely related species.
