The Abert's Towhee (Pipilo aberti) is a resident of desert thickets and riparian areas in parts of the southwestern United States and a few areas of Mexico in northern Sonora and Baja. It can be a common species in some parts of its range. The top two shots here were taken in Tucson, Pima Co., Arizona, in April, 2005. These are digital images taken with a Canon EOS 1D Mark II and EF 500mm F/4 L IS lens and 2X extender.
