Encountered this long-nosed snake constricting and attempting to eat a long-nosed leopard lizard. The leopard lizard ultimately escaped after several minutes of playing dead.

Until today, I had never seen a rattlesnake this late in the year in the Western Mojave Desert. The temperature was about 70 degrees F when I saw this little baby. It was only 7-8 inches long.

These two sidewinders were not mating, and appeared merely to be lying in a pile. The much larger sidewinder appeared to be gravid.

This snake was very inactive, and moved very little during our encounter. It was still in the same location at 1210 PDT. Air temperature was 55 F at initial encounter.
There's some question whether this could be a C. stephensi. Opinions please!

Crotalus scutulatus scutulatus. This was the same individual that I photographed on 17 Feb a few feet further southeast. Its greenish cast was more evident in the previous photographs. Compare photographs showing details on the head for both dates. The three scales between the supraoculars have the same shapes/sizes.

Crotalus cerastes cerastes. We were a bit surprised to see this snake out and about with the temperature at 55F. However, it had been a warm day

Crotalus scutulatus scutulatus. This individual displayed a defensive behavior I had never seen before from a rattlesnake. It initially postured in strike position, then hid its head under its body and went silent. It also made a slight hissing noise -- might have been inhaling to inflate its body. Perhaps because it was less mobile at 60F for typical defensive behavior?

Sidewinder. Should be C. cerastes cerastes in our area, but the tail coloring is what I would expect for C. cerastes laterorepens.

This was the fifth consecutive evening I had seen what was probably the same sidewinder lying under the same bush. It has always been there in the late afternoons, never present after dark. This is hopefully an ongoing observation of a single individual.

Two sidewinders were lying motionless together in a clump. Took this photo from about 15 ft away. When approached, the upper individual immediately fled. The lower individual was reluctant to move when we attempted to chase it off the road.
