Tricolored heron
The tricolored heron, formerly known as the Louisiana heron, is a small species of heron native to coastal parts of the Americas. The species is more solitary than other species of heron in the Americas and eats a diet consisting mostly of small fish.
Habitat, breeding, and distribution
Tricolored herons breed in swamps and other coastal habitats and nests in colonies, often with other herons, usually on platforms of sticks in trees or shrubs. In each clutch, three to seven eggs are typically laid. The tricolored heron is the second most coastal heron in the United States.The species' range follows the northeastern United States, south along the coast, through the Gulf of Mexico 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 nonbreeding visitor to the far north.
It was likely the most numerous heron in North America until the cattle egret arrived to the continent in the 1950s. While the species' population appears to be on the decline, it remains quite common. The bird is listed as "Threatened" by the Florida Fish and [Wildlife Conservation Commission].
