One of the focuses of the recent Mexico biodiversity expedition was finding these interesting Ditmars' horned lizards. I found the first one, of only two found on the entire trip. This was not a range extension, per se, but more of an infill between known ranges in the sky island region of northern Sonora.
There is a tradition that you have to kiss the first one you find and then a bottle of tequila is opened for the occasion. Out of four trips, this was the first one I ever found.
They are fascinating little creatures. Their main predators are ravens and small canids like coyotes and foxes, so they are not particularly afraid of large animals like us or cows or deer. They are quite docile and even a wild one will take a grasshopper offered to it without trying to run away.
Alt text (because the site keeps crashing): first photo is a small horned lizard sitting in the palm of my hand. Second photo is me fake-kissing the same lizard while holding it.
