Huge, long-legged, black-and-white waterbird, about the size of Great Blue Heron. Whitish body with black flight feathers. Adults have a wrinkly bald head and fairly dark bill; juveniles have paler bill and more messy feathering on head and neck. Bill is thicker and more curved than herons.
Forages mainly for fish by moving open bill through water until it feels prey. Found in wetlands, swamps and shallow ponds.
Often soars, sometimes with vultures.
