Belted Kingfisher
Megaceryle (Ceryle) alcyon
This image by Louis Agassiz Fuertes is hosted at Wikimedia where there are more great pictures of this wonderful bird.
This kingfisher was photographed by Robert Shantz at East Fork of Black River; Apache National Forest, Arizona.
Kingfishers can be found diving for small fish wherever there is open water in the Sonoran Desert. Look for them especially along major rivers and streams.
They are mostly absent from the Sonoran Desert during the summer when they head north to breed.
