The tricolored heron (Egretta tricolor), 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 bird is listed as "Threatened" by the Florida Fish and Wildlife Conservation Commission.
Description
This species measures from long and has a typical wingspan of . While other members of Egretta may also eat crabs and opportunistically forage for terrestrial arthropods, the tricolored heron has been consistently observed to be almost exclusively piscivorous, primarily feeding on members of Cyprinodontidae, Fundulidae and Poeciliidae, as well as Centropomidae and Cichlidae.
