These photos were taken on a WGNSS Nature Photography Group field trip into the St. Francois Mountains in early June, 2019.
Along with a couple of female eastern collared lizards, we found quite a few other herps of interest.
These lizards are really great photographic subjects. They are relatively easy to photograph, allowing for watching while they bask in the sunlight of a clear day without much manipulation or interference necessary.

You outdid yourself, these are spectacularly composed images.
Thank you so much, Miguel
