The little egret is a small, hyperactive ‘white heron’ with a slender black bill. First recorded from New Zealand in 1944, there are 2-3 little egrets present here most years, with single birds often staying at the same site for many consecutive years.
The little egret is a small entirely white heron, with yellow facial skin and a rapier-like black bill. Its legs and bill are black, with yellow soles to its long toes. In breeding plumage, a pair of long, slender plumes grow from the back of the head, curving elegantly down to the back, and filamentous plumes develop on the lower back and breast. The facial skin turns bright red or blue when breeding, but this has not been reported in New Zealand. Juvenile birds have greenish-black legs and duller yellow feet.
The little egret is widely distributed throughout the tropical and warm temperate regions of Europe, Africa, Asia, and Australia. It is reasonably common in most states of Australia but is listed as threatened in Victoria. The main threats to little egrets elsewhere are from coastal reclamation and wetland draining, especially in its feeding and breeding areas of Asia. In New Zealand, little egrets occur almost exclusively in estuarine habitats.
