Blue and White Reef Heron

The Pacific reef heron (Egretta sacra) are found throughout Asia and the Pacific including the oceanic region of India, Southeast Asia, East Asia, Polynesia, Australia, Tasmania and New Zealand. The species displays an unusual, non-sexual dimorphism, with some members having entirely white plumage and others (the larger portion) being charcoal-grey. The reason for the colour variation or "morph", is unknown, though it is most commonly thought to be related to camouflage. Photograph Courtesy of Oriental Bird Images
