BIRDS CREEK. Birds Creek rises just north of the DeWitt county line and two miles northwest of Westhoff in southern Gonzales County (at 29°11' N, 97°30' W) and runs east for 4½ miles to its mouth on Sandies Creek, two miles northwest of Westhoff (at 29°12'N, 97°26' W). The stream is intermittent in its upper reaches. It traverses an area of low-rolling hills and prairies surfaced by highly expansive clay that supports grass and some mesquite. Water-tolerant hardwoods grow near the mouth. The stream was named for James Bird, who obtained the original land grant in the area.
