The Green Kingfisher is a small, striking kingfisher that occurs rarely in Arizona, typically along wooded streams and rivers in the southern part of the state. It is the smallest of the three kingfishers found in the U.S., measuring about 7–8 inches in length, with short legs, a long, pointed bill, and rapid, direct flight. Males can be recognized by their dark green upperparts and a broad chestnut band across the chest, while females lack the chestnut and instead show green spotting on the breast sides.

In Arizona, Green Kingfishers are considered rare visitors, with most records coming from riparian areas in southeastern counties, especially along the San Pedro River and other suitable waterways where dense streamside vegetation provides cover. Their presence here reflects the northern edge of their typical range, which extends from southern Texas and Mexico south through much of Central and South America.

These kingfishers hunt by perching low over water and diving to snatch small fish, insects, and aquatic invertebrates. Their secretive nature and preference for quiet, shaded streams make them difficult to spot, and sightings are often highly sought after by birders in Arizona.
