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