Watched this male prairie lizard (Sceloporus consobrinus) visually defend his territory with head bobs and push ups. The area in my mom’s garden was at least 10 m long and contained 2+ females, which were in turn displaying to one another. 1/n
While all this is going on between the Young and the Restless lizards, another #squamate , a southern black racer (Coluber constrictor priapus) slipped into the garden.
I attempted a capture, but no shoes = no luck (and somehow will probably = poison ivy 😆) 3/3

🏙️#Sex biases in the individuals studied in the lab & field. Why is it more often males of a species? What data are we missing because of that bias? 🤔

Any recommendations for ways to collect data about color & pattern from images of #wildlife? We want to quantify things like %cover by a color & intensity.
Have enjoyed reading some of the work by Davis & Grayson on quantifying #color, hue, % coverage in #newts and other animals.
They used Fovea Pro, a Photoshop add in. The newer version (QIA-64) costs ~$800 😬
Am also considering the methods of Paterson & Blouin-Demers where they quantify continuous variation in throat color in #lizards using Adobe & ultimately analysis in #imageJ (but haven't had time to test it out yet)
