Species of bird

The Pacific reef heron (Egretta sacra), also known as the eastern reef heron or eastern reef egret, is a species of heron found throughout southern Asia and Oceania. It occurs in two colour morphs with either slaty grey or pure white plumage. The sexes are similar in appearance.

The Pacific reef heron is widely distributed across southern Asia and Oceania. In Australia, Pacific reef herons inhabits most of the coastline, and offshore islands including the Torres Strait Islands. Pacific reef herons are widespread across Micronesia, with breeding records in Guam, the Marshall Islands, Northern Mariana Islands, and Palau, among various other islands. The species also breeds throughout western Polynesia, including in Fiji, and Tonga – though it does not breed in Niue. New Zealand is considered to be the southern limit of the Pacific reef heron's distribution. Despite being relatively uncommon, the herons are found throughout the country, though are most common in Northland.

The species lay clutches of eggs year round in colonies in the jungle, between palms and mangroves or in cavities of old buildings. Two to three paled greenish blue eggs are laid in nests constructed from branches and blossoms. Males and females share brooding tasks. They normally have a 28 day brood period. After chicks are hatched, parents provide approximately five weeks of support.

In New Zealand, the Pacific reef heron has the conservation status of "Nationally endangered". It has been classified as "Regionally Critical" in the Wellington region.
