Costa's Hummingbird (Calypte costae); Tohono Chul Park, Tucson, AZ [Lou Feltz]
This guy (It's an adult male.) was sitting out a hot afternoon in this mesquite tree at an elevation of ~ ten ft. It allowed close approach and I suspect that the park environment had gotten him used to people. This species is found mainly in southern AZ and CA. I was surprised that the purple shows well in this fully shaded situation.
