The tricolored heron (Egretta tricolor), formerly known as the Louisiana heron, is a small species of heron that is native to coastal parts of the Americas. In the Atlantic region in ranges from northeastern United States, south along the coast, through the Mexican Gulf and the Caribbean, to northern South America as far south as Brazil. In the Pacific region it ranges from Peru to California, but it is only a non-breeding visitor to the far north.
