Adult Snowy Egrets are all white with a black bill, black legs, and yellow feet. They have a patch of yellow skin at the base of the bill. Immature Snowy Egrets have duller, greenish legs.
They are most common along the coast, though they do breed patchily in inland wetlands. Snowy Egrets nest colonially, usually on protected islands, and often with other small herons. They concentrate on mudflats, beaches, and wetlands, but also forage in wet agricultural fields and along the edges of rivers and lakes.
