I have been keeping track of a colony of Crevice Spiny Lizards (Sceloporus poinsettii) that live in a canyon near my house. The 6 individuals I monitor live on a section of wall about 50ft long. There are 3 females and 3 males.
They each have their own individual crevices which they quickly duck into when I get near.
There are also a few Sagebrush Lizards (Sceloporus graciosus) which inhabit the same area.
It is very cool to see two different species inhabit not just the same area, but also the same hides.
