The
Pacific reef heron (
Egretta sacra) is a species of heron found throughout southern Asia and Oceania. About 60 cm (24 in) in length, this species has two distinct colour
morphs, charcoal-grey (as seen here) and pure white. The bird's diet consists mainly of fish,
crustaceans and
molluscs. This Pacific reef heron was photographed at
Boat Harbour, in New South Wales, Australia.
