Pretty birds, Ed. They look like cousins of the Bee-eaters.
They are grouped with the bee eaters, rollers and the kingfishers taxonomically. I had never seen one until this trip and we got two species at once!! I immediately fell in love with them. We saw them at the same lodge several days in a row in several locations. One pair was digging a nest hole in the side of the muddy road, so they have that red Costa Rica mud on their beaks in all the photos.
