The Little Egret is a small white heron. 

The adult Little Egret is 55–-65 cm long with an 88–-106 cm wingspan. It weighs 350–-550 grams. Its plumage is all white. It has long black legs with yellow feet and a slim black bill. In the breeding season, the adult has two long nape plumes and gauzy plumes on the back and breast. The bare skin between the bill and eyes becomes red or blue. Juveniles are similar to non-breeding adults but have duller legs and feet. The subspecies garzetta has yellow feet and a bare patch of grey-green skin between the bill and eyes, whereas nigripes has yellow skin between the bill and eye and blackish feet.

Little Egrets are mostly silent but make various croaking and bubbling calls at their breeding colonies and produce a harsh alarm call when disturbed.

Its original breeding distribution was large inland wetlands and coastal wetlands in warm temperate parts of Europe, Asia, Africa, Taiwan, and Australia.

In warmer locations, most birds are permanent residents; northern populations, including many European birds, migrate to Africa and southern Asia. They may also wander north after the breeding season, which presumably has led to this egret's range expansion.

The Little Egret nests in colonies, often with other wading birds, usually on platforms of sticks in trees or shrubs or in a reedbed or bamboo grove. Pairs defend a small breeding territory, usually extending around 3–4 m from the nest. The three to five eggs are incubated by both adults for 21–25 days to hatching. They are oval in shape and have a pale, non-glossy, blue-green colour. The young birds are covered in white down feathers, are cared for by both parents and fledge after 40 to 45 days.

This egret stalks its prey in shallow water, often running with raised wings or shuffling its feet. It may also stand still and wait to ambush prey. It eats fish, insects, amphibians, crustaceans, and reptiles.
