There are three types of Kingfishers in America--the Ringed, Belted and the Green. The Belted is the one that you're used to seeing if you live, well, just about anywhere in America. The other two--the Ringed and the Green--live exclusively in South Texas.
The Green Kingfisher is pretty small (only 7-8 inches tall), which makes the giant bill look pretty hilarious. I always kind of wonder why they're not top-heavy--I'm half-expecting this one to tip over as I'm taking the picture. This one happens to be female. The adult male has a red chest instead of a green and white one. I took this picture at Estero Llano Grande State Park on September 15, 2012.
