The Amazon Kingfisher is a resident of lakeshores and large-slow flowing rivers from northern Mexico south to central Argentina. They are large dark bronzy green birds with a ragged crest, a white throat and collar, and a white belly; the breast of the male is rufous breast, while the female has a narrower green breastband. Amazon Kingfishers are superficially similar to the Green Kingfisher Chloroceryle americana, but are much larger with a heavier bill, and typically forage from more conspicuous perches. Amazon Kingfishers hunt fish and crustaceans from a perch, diving into the water to catch their prey and then returning to the same perch before stunning their prey and swallowing it head first. These kingfishers also occasionally hover above the water before diving to catch prey. The nests are excavated by making tunnels into road cuts or erosion gullies near water.
