Snowy Egret with two chicks. Pickney Island NWR, South Carolina.
Males establish nesting territories and choose nest sites within the thick vegetation of a breeding colony. The nest is usually in the top or outer branches of a woody vine, shrub, or tree.
The male starts working on a nest before finding a mate. Then the female takes over and ends up doing most of the nest building, with materials supplied by the male. The nest is a shallow oval of loosely woven twigs, small sticks, grasses, sedges, rushes, and Spanish moss, about 14–18 inches across and 8–13 inches high.
