Expressly examining Cliff Swallow colonies for Cave Swallows. I discovered the State's first nesting in adjacent Comanche County 2 years ago. Saw Cave Swallows along this HWY March 2012 at the Kiowa/Comanche Co. line but could not confirm at the time. Today went looking at likely prospects. The second site hosted at least 6 (possibly 12) birds among 80 Cliff Swallows. A dozen old/used nest structures within culverts consistent with cave Swallow although none in use a present. These birds were only recent arrivals in response to heavy area rains 17 April.

30 years ago Cave Swallows were only found nesting in southwest Texas. This species has expanded its nesting range significantly. @upupamartin and I found a small colony of about 20 Cave Swallows nesting in a culvert under U.S. 83 south of Aspermont, Texas. Note the buffy throat (rather than the chestnut colored throat of Cliff Swallow) and the darker forehead patch than Cliff Swallow.
