Herons, Bitterns, and Egrets

Geographical Range
The general range for this bird group extends from the upper regions of the United States down to Mexico and Central America. These birds generally live in the northern areas of the United States and into Canada in the summertime, migrate through the middle and southern regions of the United States, and then live in Mexico and Central America in the winter. They generally live along the coasts year-round including the coast of California, south of Virginia, and along the Gulf.

Some exceptions include the Great Blue Heron which live in the majority of the United States year-round, the Little Blue Heron, the Tricolored Heron, and the Yellow-crowed Night Heron which live in the south east quarter of the United States, and the American Bittern which is only seen along the Pacific coast year-round.

Common Features
All are wading birds found in marshes and wetlands. They are carnivores with a diet consisting mostly of amphibians, reptiles, insects, and fish.

The general body shape consists of a stocky body with a long neck and bill and long legs with un-webbed feet. Many also have the ability to retract and extend their neck.

Differences
All three are in the same family, but only bitterns are taxonomically different. There is no real taxonomic difference between a heron and an egret. The main difference is in a generalization that egrets tend to be all white and have wispy feathers.

Bitterns also tend to nest in reed beds along the water while herons and egrets rest in trees.
