Western Reef-Heron

The Western Reef-Heron is a medium-sized, coastal heron closely related to the Little Egret, occurring in two distinct color morphs: a dark slate-grey morph, often with a white throat patch, and a pure white morph. Both morphs share a stout, mostly dark bill (often with a yellowish base) and dull yellow-green legs, distinguishing them from the more slender, all-black-billed Little Egret.

Breeding birds develop long, wispy nape plumes similar to those of egrets. This species is a true coastal specialist, rarely venturing far from tidal mudflats, mangroves, and rocky shorelines.

Key field marks

• Two color morphs: dark slate-grey (sometimes with white throat) and pure white
• Stouter bill than Little Egret, often with a paler or two-toned base
• Dull yellow-green legs and feet, less contrastingly bright than the Little Egret's black legs and yellow feet
• Strictly coastal habits

Similar species

The white morph is easily confused with the Little Egret, but the reef-heron's heavier bill, duller leg color, and strictly coastal habitat help separate them. The dark morph can suggest a small dark heron but is told by its egret-like shape and bill structure.

Habitat

This species is almost exclusively coastal, favoring tidal mudflats, mangrove creeks, rocky reefs, and estuaries, rarely straying inland.

Range and migration

It occurs along the coasts of West Africa and across the northern Indian Ocean, including the Red Sea, Persian Gulf, and coastal South Asia. Most populations are resident, with some local dispersal.

Behavior

Western Reef-Herons forage actively, often running through shallow water with wings raised or half-spread to flush prey, a more dynamic hunting style than the sit-and-wait approach of many herons.

Voice

A harsh croaking call, similar to other small herons and egrets, given mainly when disturbed or at breeding colonies.

Feeding

It feeds on small fish, crabs, shrimp, and other invertebrates gleaned from tidal pools, mudflats, and shallow coastal water.

Nesting and breeding

Colonial nester, often alongside other herons and egrets, building stick nests in mangroves or coastal scrub; clutches typically contain 2-4 eggs.
