Striated Heron

The Striated Heron is a compact, short-legged heron with a dark, greenish-grey cap and back, grey underparts, and a black crest that can be raised when alert. Its short yellow-to-orange legs and hunched posture give it a distinctive stocky, low profile compared to taller herons.

This is one of the most widely distributed heron species in the world, found along tropical and subtropical coastlines, mangroves, and rivers across Africa, Asia, Australia, and the Americas, with numerous regional subspecies. It is best known among birdwatchers for its remarkable tool-using behavior: some individuals drop bait, such as insects, feathers, or bread, onto the water's surface to attract fish within striking range.

Key field marks

• Small, stocky body with short legs and hunched stance
• Dark greenish-grey crown, crest, and back
• Grey underparts and neck
• Yellow-orange legs, brightening to orange-red in breeding condition

Similar species

The Green Heron of the Americas was formerly considered the same species and looks very similar but shows a chestnut neck rather than grey; the two are now generally treated as separate species with limited range overlap. Juveniles are streaky brown and can be confused with young night-herons but are smaller and more compact.

Habitat

Striated Herons favor mangroves, tidal mudflats, riverbanks, and other well-vegetated shorelines, usually staying close to cover.

Range and migration

The species has an enormous pantropical range across coastal Africa, southern Asia, Australasia, and parts of South America, and is largely sedentary, though some populations make local movements.

Behavior

This is a patient, solitary hunter that crouches motionless at the water's edge, often nearly flat against a branch or rock, before striking with lightning speed. Its use of bait to lure fish is one of the few well-documented examples of tool use among birds.

Voice

A sharp, explosive "skeow" or "kyow" alarm call, given when flushed.

Feeding

Small fish, crabs, and aquatic insects are captured with rapid strikes from a crouched ambush position at the water's edge.

Nesting and breeding

Pairs nest solitarily or in loose groups, building a small stick platform in mangroves or waterside trees, and typically lay 2-5 eggs.
