I noticed something moving on the RV drive last evening after some thundershowers. I thought it looked like a frog. We took photos of it while it was climbing up the slope behind the drive.
After a little research this afternoon, we believe it is a Colorado River Toad, a.k.a. Sonoran Desert Toad. It matches the description given in Wikipedia for such toads.
We have long heard that desert toads respond to thunder and come out of their burrows to look for pools in which to spawn. This is our first encounter with a desert toad.

From Wikipedia
The Colorado River toad, Bufo alvarius, also known as the Sonoran Desert toad, is a psychoactive toad found in northern Mexico and the southwestern United States. Its skin and venom contain 5-MeO-DMT and bufotenin.
The Colorado River toad can grow to about 7.5 inches (190 mm) long and is the largest toad in the United States apart from the non-native cane toad (Bufo marinus). It has a smooth, leathery skin and is olive green or mottled brown in color. Just behind the large golden eye with horizontal pupil is a bulging kidney-shaped parotoid gland. Below this is a large circular pale green area which is the tympanum or ear drum. By the corner of the mouth there is a white wart and there are white glands on the legs. All these glands produce toxic secretions. Dogs that have attacked toads have been paralyzed or even killed. Raccoons have learned to pull a toad away from a pond by the back leg, turn it on its back and start feeding on its belly, a strategy that keeps the raccoon well away from the poison glands.
I think they respond, not so muich to thunder, but to the ground becoming wet. Regardless, do not lick them, or your fingers, after handling one. That could be either a great high or a very bad trip. Their secretions contain Bufotenin and it is a powerful hallucinogen. That they are found in your location is amazing but not surprising to me. I found many of them near places very remote from any rivers. They certainly are neat toads and are one of the largest I have ever seen.
All the best,

The funny thing is, I want one specimen of a psychoactive plant, that being the Peyote (lLophophora williamsii). My brother-in-law, who is a Sheriff, said that he would trust me with it, as he knows that it would be nothing more than a notorious member of my cactus collection. I would not actually use it.
I am pretty amazed by the Wikipedia section on this toad entitled venom and US law. I can’t imagine why anyone would want to take a trip on toad venom, Eewwww! 😯
