OK, I give up...I can't find a range for these things on the internet, and half the stuff i saw showed the wrong names and wrong lizards...go figure...

Well, it isn't the same place, just nearby. The line's got to be somewhere, so why not in Grand County? FWIW, the nearby yellow-chinned population was uniformly yellow-chinned (out of 20 or so individuals...); I think this population is supposed to be uniformly white-chinned, but I only saw one individual (and this is about as much as I saw of him) so I don't know.

I think those researchers are on drugs. You can't have both lizards in the same place...perhaps the yellow varies from lizard to lizard and has nothing to do with the species...

Some collared lizard researchers I was with told me this population was Crotaphytus collaris baileyi. As I recall, the distinction invoked was that males of subspecies auriceps have completely yellow heads, while these guys have heads yellow on top, but white "chins".

I haven't seen a huge amount of Crotaphytus collaris baileyi, though; just this guy and a couple in northwestern New Mexico that I can think of.

Hi Patrick. How can you have a W and an E collard in the same county and both have yellow heads? Did you boo boo?
