First ornatus I have ever seen in Bexar county.
This is a screen capture from an 8mm home movie (since converted to digital) I took as a teenager in 1967 at Philmont Scout Ranch in Colfax Co., NM. Lousy images, but perhaps of some minor interest since it is nearly 50 years ago.
Several were observed in the area. All medium sized and thin.
Sé que debo describir, pero comento que era más bonito el nombre anterior:
Crotalus durissus tzabkan
Crotalus is a genus of venomous pit vipers found only in the Americas from southern Canada to northern Argentina. The name is derived from the Greek word krotalon, which means "rattle" or "castanet", and refers to the rattle on the end of the tail which makes this group (genera Crotalus and Sistrurus) so distinctive. 32 species are currently recognized.
