Cruising around a few nights earlier revealed a Grey Fox and  a Great-Horned Owl, but no snakes. We hypothesize that the reason for the reptilian absence was due to nighttime temperatures around 60F. The temperature during the drive this weekend, however, was close to a balmy 70F.

Sure enough, Mines Road (and possibly the weather) did not disappoint. About 10 minutes down the road from the Tesla Road turnoff, we found a little-over-a-foot-long Western Rattlesnake slowly crossing the road.

Further down the road, we encountered a snake we had been looking for for quite a while: a California Kingsnake, and a big one at that. This one cruised across the road fairly quickly, but we were still able to get some pictures.

Even further along the road, our tires almost screeched to a halt over a second California Kingsnake, this one much smaller and much more reluctant to leave the warm road (it eventually did with some help).

To top the night off, on the drive back, we found another Western Rattlesnake crossing the road, bringing our tally to four snakes total – two king and two rattle.

While seeing snakes on the road is exhilarating, the excitement is bittersweet. Snakes are constantly killed on roads, so if you can, please try and be careful when driving.

Along Mines Road you encounter a lot of chaparral habitat. At one point a stream crosses Mines Road. This is a annual stop to check for tadpoles and indeed there were plenty of them. There were Western Toad tadpoles and Northern Pacific Treefrog tadpoles. The toad tadpoles, which were very dark, were present in large numbers.

Wildflowers are everywhere in San Antonio Valley. There are vast expanses filled with lupines, poppies, California buttercups and other species. And they are framed by the majestic oak trees. On prior trips Tule Elk, Coyote and Lewis Woodpecker have been seen here.

At a serene farm pond by the roadside, there was a pair of Ring-necked Ducks.

The highlight of the trip was a California Red-sided Garter Snake. It was sunning itself on top of one of the large corrugated metal pipes under a culvert. Garter Snakes are hard to identify and this identification is based on much consultation with the excellent site – www.californiaherps.com. Let me know if you have anything to add.

Other sightings along the way included  several Black-tailed Jackrabbits, Desert Cottontail, Black-tailed Deer, a few pairs of Wood Ducks, flocks of Wild Turkeys, Yellow-billed Magpies, California Thrasher, California Quail, Acorn Woodpecker.

The main highlight of the day was a herd of Tule Elk resting under some trees in San Antonio Valley. They were quite close to the road, and easily seen from the car.

Other mammal highlights included both Desert Cottontail and Black-tailed Jackrabbit off of Mines Road. Birdwise, I saw a Greater Roadrunner and a California Thrasher, both very interesting species that aren’t seen often. I also saw a pair of Turkey Vultures feeding off of a California Ground Squirrel carcass on the road and took this picture:

While they are quite common, Turkey Vultures are still quite a sight to see close up.
