The Tricolored Heron (Egretta tricolor) formerly known in North America as the Louisiana Heron, is a small heron. It is a resident breeder from the Gulf states of the USA and northern Mexico south through Central America and the Caribbean to central Brazil and Peru. There is some post-breeding dispersal to well north of the nesting range.
A medium-sized (26 inches) wader, the Tricolored Heron is most easily identified by its contrasting white belly and slate-gray body. Other field marks include a rusty-brown neck, white rump, and long dark bill. Male and female Tricolored Herons are similar to one another in all seasons. The Tricolored Heron breeds along the Atlantic and Gulf coasts of the United States from Texas to southern Maine, and breeds further inland in Florida. In winter, this species withdraws from the northern part of its range, and may be found in the southern part of its east coast range, along the coast of Southern California, and inland in Mexico and Central America. Non-migratory populations also exist along the coast of Central and South America. Tricolored Herons breed in a number of wetland habitat types, including freshwater and saltwater marshes, coastal lagoons, and estuaries. This species may also be found in Mangrove wetlands in parts of its range where this habitat occurs, particularly in winter. Tricolored Herons mainly eat fish, but may also take crustaceans and small vertebrates (such as frogs, lizards, and mice) when the opportunity arises. Tricolored Herons 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 Tricolored Herons returning to trees to roost at sunset, or while flying with their feet extended and their necks pulled in. Tricolored Herons are primarily active during the day.
