The tricolored heron is a midsized member of the genus Egretta. This species can reach a length between 24-26 inches (61-66 centimeters) with a wingspan of approximately 36 inches (91 centimeters). The tricolored heron is named for its distinct coloration. It has a dark slate-blue colored head and upper body, a purple chest, and white underparts. This species also has a long, slender neck and bill, and is the only dark heron with light underparts.

The diet of the tricolored heron primarily consists of fish.

Tricolored herons breed in colonies between the months of February and August. Females construct nests out of sticks and vegetation collected by the males. Nests are found in trees or shrubs on salt marsh islands or standing water. Females lay between three to five eggs and both parents share incubation duties. Eggs hatch approximately 21-25 days after being laid (LaLonde 2003). The young remain in the nest until they are approximately 35 days old.

Tricolored herons inhabit fresh and saltwater marshes, estuaries, mangrove swamps, lagoons, and river deltas (Frederick 1997). They can be found from Massachusetts, down through the Gulf of Mexico and Caribbean, to northern Brazil. Breeding sites can also be found on the Pacific Coast from Baja California down to Ecuador. Tricolored herons are widespread, permanent residents in Florida, although they are less common in some parts of the Panhandle.
