Egretta caerulea


This small heron feeds on aquatic invertebrates, fish, reptiles, and amphibians. Because this heron doesn't have the long and fancy plumage feathers that the egrets have, it's been spared from feather hunters.


Medium sized bird with bluish-gray body plumage. Reddish head and neck. Long, pointed blue-gray bill with a black tip. Dull green legs. Sexes similar. Holds it's neck in an "S" curve while at rest and when in flight. Immature bird has white plumage, gray lores, blue-gray primary tips, and black tipped bill with gray, yellow, or flesh colored base. Black wings with white wingbars. Black, notched tail. White rump and undertail coverts. White edges on wing and tail feathers. Pale bill and legs. Male (Winter): Yellow parts are duller and grayer.
