Reef heron is a medium-sized bird from the heron family. It lives on the coasts and islands of the Indian Ocean and exists in two color forms: white and dark gray.
Reef heron differs from other herons by having two color forms in one species. It is important for nature because it regulates the population of small animals on coastlines and serves as an indicator of the health of marine shallows.
