Intermediate Egret


The Intermediate Egret, Median Egret, or Yellow-billed Egret (Mesophoyx intermedia) is a medium-sized heron. It is a resident breeder from east Africa across tropical southern Asia to Australia. It often nests in colonies with other herons, usually on platforms of sticks in trees or shrubs. Two to five eggs are laid, the clutch size varying with region. This species, as its scientific name implies, is intermediate in size between the Great Egret and smaller white egrets like the Little Egret and Cattle Egret, though nearer to Little than Great. It is about 90 cm tall with all-white plumage, generally dark legs and a thickish yellow bill. Breeding birds may have a reddish or black bill, greenish yellow gape skin, loose filamentous plumes on their breast and back, and dull yellow or pink on their upper legs (regional variations). The sexes are similar.
Some taxonomists put this species in the genus Egretta or Ardea.

The Intermediate Egret stalks its prey methodically in shallow coastal or fresh water, including flooded fields. It eats fish, frogs, crustaceans and insects.
