This past summer we put out extra saucers of water around the back yard to help birds and animals weather the drought. Birds we had not seen here showed up to enjoy our hospitality. The Curve Billed Thrasher was one of the most striking with their intense yellow eyes and lovely song.

According to All About Birds the Curve Billed Thrasher is native to the southwest and northern Mexico. It prefers to live in cactus and spiny brush so they might have spent their summer in the stand of prickly pear and oaks in the back yard.
Update 12/13/2012 - These birds have been identified as Long-Billed Thrashers. An important difference as they are only found here in south Texas. Please reference the update here and check Sam Taylor's reply in the comments section.
