This afternoon at lunch, quite a commotion arose in the big pecan. First a couple of tufted titmice began flying erratically and tweeting incessantly. They were soon joined by three or four black-crested titmice and a summer tanager. The focus of their attention was the crotch between two large branches. It seems that there was an intruder in the tree. This small Texas rat snake was hiding its head from all the harassment.
