Before we birded in the area of Parque Nacional Sierra de San Pedro Martir and after we stopped at the Santo Tomas Winery, we birded along several streams. It was at one of these stops that we saw the Granite Spiny Lizard. The Granite Spiny Lizard (Sceloporus orcutti) is between 7.6 and 10.8 cm long. Its dorsal scales are strongly keeled and pointed on its body and tail. It has a wide purple mid-dorsal stripe. The male of the species has yellow-green and blue centered scales on its body; juveniles and females have distinct yellow-tan transverse bands on their body and tail. Additionally, the male S. orcutti has deep blue ventral patches on its chest, throat, and femoral pores. It was a partly cloudy day with temperatures in the mid- to high 70's.
