Pacific Reef-Heron

The Pacific reef heron, also known as the eastern reef heron or egret, is a medium-sized heron 57–66cm long with a wingspan of 90–110cm and an average weight of about 400g. It occurs in two colour morphs, slaty grey or pure white, an unusual non-sexual dimorphism, with the larger share of birds charcoal-grey. It is found throughout southern Asia and Oceania (Wikipedia, general species account).

It is widespread across Micronesia, with breeding records in Guam, the Marshall Islands, the Northern Mariana Islands and Palau, and breeds throughout western Polynesia including Fiji, French Polynesia and Tonga. Two to three pale greenish-blue eggs are laid in nests constructed from branches (Wikipedia, general species account).
