Snowy Egret
Egretta thula
Summary 7
The snowy egret (Egretta thula) is a small white heron. The genus name comes from the Provençal French for the little egret aigrette, a diminutive of aigron, "heron". The species name thula is the Araucano for the Black-necked Swan, applied to this species in error by Chilean naturalist Juan Ignacio Molina in 1782.

Smaller (20-27 inches) than North America’s other light-colored herons and egrets, the Snowy Egret is most easily identified by its black bill, black legs, yellow feet, and regal breeding plumes. Other field marks include an all-white body, short tail, and small yellow skin patch on the face. Male and female Snowy Egrets are similar to one another in all seasons. The Snowy Egret breeds along the east coast of the United States north to Maine and locally in the interior southeast and west. Coastal birds are non-migratory, while interior birds migrate to the Atlantic and Gulf coasts, the Pacific coast of California and in the interior from northern Mexico south to Panama. Other non-migratory populations occur along both coasts of Mexico and Central America as well as in the West Indies. Snowy Egrets live in and around small bodies of water. In summer, Snowy Egrets nest in colonies, called ‘rookeries,’ in trees surrounding lakes and ponds. This species utilizes similar habitats during the winter. Snowy Egrets mainly eat fish, but may also take crustaceans and small vertebrates (such as frogs, lizards, and mice) when the opportunity arises. Snowy Egrets may be best observed wading in shallow water, where they may be seen plunging their bills into the water to catch fish. It is also possible to see Snowy Egrets at their rookeries, especially when they return to roost at sunset, or while flying with their feet extended and their necks pulled in. Snowy Egrets are primarily active during the day.
