this is as much of a Mohave Rattlesnake, know as a "Mohave Green" around here, as I could see, and I was grateful to see it as I was just about to step where it was resting...its flat diamond-shaped head is at the lower right, partially hidden by a branch of the rosemary bush it was emerging from under...it has two venoms, one a "regular rattlesnake venom" and the other a cobra-like paralyzer...there are few reports of its bites, apparently mostly from people messing with them...this one did not seem threatened by me; when I quietly came back with my camera it did not coil or rattle, just stayed absolutely still...when I went out again to check on it 15 minutes later, it had disappeared...and I do not know if it went into the rosemary bush or departed...
...the other creature news of the day is that I discovered I now have TWO roadrunners roosting at night in the Caroline Jasmine vine, and I was able to get images of them just as they are about to go to roost, carrying little sticks...
