The Cactus Wren (Campylorhynchus brunneicapillus) is native to the southwestern U.S. The Cactus Wren is the largest Wren we have in the United states. Its marked white eyestripe, brown head, barred wings and tail, and spotted tail feathers make it easy to identify. I've had families of Cactus Wrens in my yard for almost 15 years. This photo was taken in June of 2011.
