The herons are long-legged freshwater and coastal birds in the family Ardeidae. There are 64 recognised species in this family. Some are called "egrets" or "bitterns" instead of "heron".

Egretta is a genus of medium-sized herons, mostly breeding in warmer climates. Representatives of this family are found in most of the world, and the Little Egret, as well as being widespread throughout much of the Old World, has now started to colonise the Americas.

These are typical egrets in shape, long-necked and long-legged. There are few plumage features in common, although several have plumes in breeding plumage; a number of species are either white in all plumages, have a white morph (e.g. Reddish Egret), or have a white juvenile plumage (Little Blue Heron).

The breeding habitat of Egretta herons is marshy wetlands in warm countries. They nest in colonies, often with other wading birds, usually on platforms of sticks in trees or shrubs.

These herons feed on insects, fish and amphibians, caught normally by cautious stalking.

Little Egret, Egretta garzetta  

               

The Little Egret forms a superspecies with the Snowy Egret (Egretta thula) with the Little Egret being present
in the Old World while the Snowy Egret is found in the New World.

It is partially migratory with more northern populations migrating south during the northern winter.
