The green heron is a small, compact American heron that often disappears against shaded wetland vegetation. Adults combine a dark greenish back with a chestnut neck and a sharp, straight bill. Florida supports resident birds as well as seasonal arrivals. Unlike large herons that commonly stand in open shallows, this species often hunts from low branches, roots or banks, making quiet attention to the water's edge more useful than broad scanning.

A green heron commonly waits motionless above shallow water, then extends its folded neck in a rapid strike. It also walks carefully along branches and muddy edges, changing position when prey remains scarce. Some individuals deliberately place bait on the surface to attract fish. Nesting usually occurs in shrubs or trees, singly or in loose groups. Disturbed birds may raise their crowns, flick their tails and depart with a sharp call. When alarmed or taking flight, the green heron often emits a distinctive, sharp 'skeow' call. Their flight pattern is characterized by slow, deliberate wing beats, often close to the water surface or through dense vegetation.

• Some individuals use insects, feathers or other objects as fishing bait.
• A folded neck makes the bird appear much shorter than it does while striking.
• Its dark back can look almost black until light reveals the green sheen.
• Both parents incubate eggs and feed the chicks.

Green herons can be watched in Florida throughout the year. Spring and summer bring breeding activity and additional migrants, while quieter winter wetlands still hold residents. Early morning or late afternoon often offers better activity and gentler light than the hottest midday hours. During the breeding season, green herons typically lay 2 to 6 eggs, which hatch after about 19 to 21 days. Outside of Florida, some northern populations migrate south for the winter, while Florida residents are generally year-round.

It uses mangroves, freshwater marsh margins, wooded ponds, canals and sheltered estuaries. Dense cover beside shallow water is particularly valuable. In Florida, natural wetlands and some urban waterways both provide habitat, provided there are secure perches, prey and suitable nesting vegetation nearby. This adaptable species is often found in both brackish and freshwater habitats throughout its range. It particularly favors areas with emergent vegetation like cattails or reeds, which provide excellent camouflage.

Small fish form the core of its diet, with crustaceans, aquatic insects, frogs and other small animals also taken. Hunting is usually close to cover rather than far out in open water. Prey is captured with a sudden bill thrust and swallowed whole. Green herons have an exceptionally long and flexible neck, allowing them to strike prey with surprising speed and reach from elevated perches. They are known to drop leaves or insects onto the water surface, observing and striking at fish drawn to the disturbance.

Identification

Adults differ from night herons in their smaller size, chestnut neck and greenish back, while juveniles are slimmer and finer-billed than juvenile black-crowned night herons. The adult green heron's plumage appears dark overall at a distance, but closer views reveal rich chestnut on the neck and sides, and a glossy, dark greenish-blue cap and back. Their short, yellow legs and feet are also a good identifying feature, contrasting with their darker body.
