Cassin's Sparrow
Aimophila cassinii
The Cassin's Sparrow (Aimophila cassinii) is a widespread sparrow of scrub lands and desert grasslands of the western half of Texas, and parts of Arizona, New Mexico, Colorado and Kansas. Its song can be commonly heard during the spring and summer in much of south and west Texas. The Cassin's Sparrow shown here was a singing male photographed in April, 2002, on a private ranch in Kenedy Co., Texas with a Canon EOS 1V and Canon EF 500mm F/4 L IS lens with a 2X extender from a Gitzo tripod on Fuji Velvia pushed one stop.

The images at right were taken of territorial birds during late spring, 2006, in Hidalgo Co., Texas with a Canon EOS 1D Mark II and EF 600mm F/4 L IS lens and 2X extender.
