Green Heron


IUCN Conservation Status: Least Concern

From a distance, the Green Heron is a dark, stocky bird hunched on slender yellow legs at the water’s edge, often hidden behind a tangle of leaves. Seen up close, it is a striking bird with a velvet-green back, rich chestnut body, and a dark cap often raised into a short crest. These small herons crouch patiently to surprise fish with a snatch of their daggerlike bill. They sometimes lure in fish using small items such as twigs or insects as bait.

Keys to identification Help

Typical Voice
  • Size & Shape

    Compared with most herons, Green Herons are short and stocky, with relatively short legs and thick necks that are often drawn up against their bodies. They have broad, rounded wings and a long, daggerlike bill. They sometimes raise their crown feathers into a short crest.

  • Color Pattern

    From a distance Green Herons look all dark. In better light they are deep green on the back with a rich chestnut breast and neck. The wings are dark gray. Juveniles are browner, with pale streaking on the neck and spots on the wings.

  • Behavior

    Green Herons stand motionless at the water’s edge as they hunt for fish and amphibians. They typically stand on vegetation or solid ground, and they don’t wade as often as larger herons. In flight these compact herons can look ungainly, often partially uncrooking their necks to give a front-heavy appearance.

  • Habitat

    Green Herons live around wooded ponds, marshes, rivers, reservoirs, and estuaries.

Similar Species

The Green Heron’s combination of small size, stocky shape, and dark coloration help make it easy to recognize. Least Bitterns are smaller and straw-colored on the neck and wings. American Bittern is substantially larger, thicker-necked, streaked with buff and brown, and lacks the Green Heron’s dark cap. Black-crowned Night-Herons and Yellow-crowned Night-Herons are slightly larger, with thicker, shorter bills than Green Herons. Adult night-herons are mostly pale gray; juvenile night-herons lack the reddish-brown-toned neck of a juvenile Green Heron. Larger herons and egrets such as the Little Blue Heron are more slender, with longer legs and neck, giving them a distinctly different silhouette.

Backyard Tips

Green Herons sometimes pay visits to ornamental fish ponds. A length of drain pipe placed in the pond can provide fish with a place to hide from feeding herons.

Find This Bird

Green Herons are common and widespread, but they can be hard to see at first. Whereas larger herons tend to stand prominently in open parts of wetlands, Green Herons tend to be at the edges, in shallow water, or concealed in vegetation. Visit a wetland and carefully scan the banks looking for a small, hunch-backed bird with a long, straight bill staring intently at the water. Their harsh skeow call is also a good clue. Green Herons are also distinctive in flight, with slow beats of their rounded wings making them look a bit like a tailless crow. Their habit of often briefly unfolding their neck during flight helps make them recognizable, too.
