Egretta sacra (Gmelin, 1789)

Common Name: 
Pacific Reef Heron

Widely distributed across southern Asia and Oceania. In Australia, the species inhabits most of the coastline and offshore islands, including the Torres Strait Islands.

Ecological Notes: 

Prey items include fish and other small aquatic animals. It will sometimes stand quietly with wings spread to attract fish to the shade and/or reduce glare from the water surface. Prey, when within range, is captured by a sudden jabbing down action.

Additional Notes: 

The species displays an unusual, non-sexual dimorphism, with most individuals possessing charcoal-grey plumage, whilst others have entirely white plumage.
