Scientific classification

Egretta
Egretta
White-faced Heron, Egretta novaehollandiae with a frog

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.

Egretta
Little Egret Egretta garzetta in Kolleru, Andhra Pradesh, India.

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.

Taxonomy

As with other heron groupings, the taxonomy of these birds has been a source of dispute. Some of these species have been placed with the great herons in Ardea, and conversely the large white species like Great Egret are occasionally allocated to Egretta.

The fact that some of the group are named as “heron” and some as “egret” has no taxonomic significance.
