The eastern reef heron is a medium-sized seabird from the heron family. It lives on coral reefs and rocky shores of warm seas and has two color forms — dark and white.
The eastern reef heron differs from other herons by its habit of living on marine reefs and the presence of two color morphs. It is important for nature because it controls the population of small marine animals and serves as an indicator of coastal ecosystem health.
