Green Herons are a solitary and secretive bird that's stocky, dark colored, and small for a heron. The adult Green Heron has a dark rufous neck, gray belly, and dark, iridescent, greenish-blue back. The upper mandible of the bill is dark, and the legs are bright orange. The juvenile has a brown-and-white streaked neck, slight crest on its dark head, and prominently light-tipped wing coverts. Yellow spectacle-shaped markings surround the eye and extend to the bridge of the bill. These markings are present, but less pronounced, in the adult.
