Details

The flat-tailed horned lizard (Phrynosoma mcalli) is a desert lizard found in parts of southwestern Arizona, southeastern California and northern Mexico. There is considerable concern about its conservation status. The species is cryptically colored and has the habit of burying under the sand when approached, making it difficult or impossible to obtain a complete count (Grant and Doherty 2007).

A total of 68 individuals were captured 134 times. Exactly half of the individuals were recaptured exactly only once. This dataset is also includedin the secr package.
