During a post-Thanksgiving visit to friends who live in the Texas Hill Country about 50 miles WNW of San Antonio, I was surprised to find this large adult male Baird's Ratsnake (Elaphe bairdi) stretched across a backroad about 15 meters above a still-running creek.
The temperatures during the preceding several days had been mild and the air temperature at midday when he was found was 75F. The elevation is ca. 1330 feet and the macrohabitat suggested Texas Rats (E. obsoleta lindheimeri) somewhat more than bairdi (both occur in the general area but are presumed to be separated by habitat differences). This date (25 NOV) is my personal latest of season for activity in this species. Typical of the species, he was extremely mild-mannered and the photos fail to do him justice.
