(''Egretta thula'')—a medium-sized heron that shares the same habitat as the great egret—is one such species. The snowy egret is readily distinguished from the great egret because it is noticeably smaller, and it has a more slender bill which is black in color and yellow feet, whereas the great egret has a yellow bill and black feet. Another species that—in North America—is easily confused with the great egret is the white morph of the

s, preferably at height of . It begins to breed at 2–3 years of age by forming monogamous pairs each season. Whether the pairing carries over to the next season is not known. The male selects the nest area, starts a nest, and then attracts a female. The nest, made of sticks and lined with plant material, could be up to 3 feet across. Up to six bluish green eggs are laid at one time. Both sexes incubate the eggs, and the incubation period is 23–26 days. The young are fed by regurgitation by both parents and are able to fly within 6–7 weeks.

Diet

The great egret forages in shallow water or in drier habitats, feeding mainly on fish, frogs, other amphibians, mice, small reptiles, crustaceans and insects
