Greater Short-horned Lizard
Phrynosoma hernandesi
The Greater Short-horned Lizard (Phrynosoma hernandesi) occurs across much of the western United States, but it can be fairly uncommon and local in distribution. The Greater Short-horned Lizard (Phrynosoma hernandesi) is often mistaken for its close relative the Pygmy Short-Horned Lizard (Phrynosoma douglasii) which has the same basic body type consisting of small pointed scales around the head and back. Until recent mitochondrial DNA evidence, P. hernandesi was considered to be the same species as P. douglasii. They are now considered distinct species with the Pygmy Horned Lizard (P. douglasii) occupying the northwest portion of the United States and extreme southern British Columbia. The individual in the top four images on the right was photographed in a spot known as Elbow Canyon in the Davis Mountains of west Texas in Jeff Davis County, in June, 2005. It was photographed with a Canon EOS 1D Mark II and EF 300mm F/4 L IS lens and 2X extender.
The Greater Short-horned Lizard in the next five shots is apparently of the subspecies known as Hernandez's Short-horned Lizard (P. h. hernandesi). This individual was on the Brett Gray Ranch, a Nature Conservancy property, in Lincoln Co., Colorado, in July, 2011. These shots were taken with a Canon EOS 1D Mark IV and a Sigma 50-500mm lens and Canon 580 flash.
