Tricolored Heron

Egretta tricolor

Summary 80

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 United States 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.

Behavior and diet 81

The tricolored heron stalks its prey in shallow or deeper water, often running as it does so. It eats fish, crustaceans, reptiles, and insects.

Description 81

This species measures from 56 to 76 cm (22 to 30 in) long and has a typical wingspan of 96 cm (38 in). The slightly larger male heron weighs 415 g (14.6 oz) on average, while the female averages 334 g (11.8 oz). It is a medium-large, long-legged, long-necked heron with a long, pointed, yellowish or greyish bill with a black tip. Its legs and feet are dark.

Adults have a blue-grey head, neck, back, and upper wings, with a white line along the neck. The belly is white. In breeding plumage, they have long, blue, filamentous plumes on their heads and necks, and buff ones on their backs.

Summary 82

The tricolored heron (Egretta tricolor), formerly known as the Louisiana heron, is a small species of heron native to coastal parts of the Americas; in the Atlantic region, it ranges from 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.

Ecological benefit 83

The tricolored heron thrives primarily in mangrove ecosystems, which are threatened by changing environmental conditions. Mangroves can be affected and even threatened by climate change, sea level rising, pollution, and much more. Since factors, such as water level can affect nesting and offspring survival rates of the tricolored heron, this bird can be used as a biological indicator species. By monitoring the health of the heron, the health of the environment can be monitored as well.
