California Striped Racer

Pine Ridge Trail, Ventana Wilderness, Monterey County, California
California Striped Racer (Coluber lateralis lateralis)
August 23 was a good day for snakes on Pine Ridge Trail. We saw this speedy fellow, a California Kingsnake, and a Gopher Snake, and we just missed seeing a rattlesnake on the trail.

California Striped Racer (Coluber lateralis lateralis)
My friend Fred Harer and I spotted this very young California Striped Racer as it slithered towards cover under a small plant on the hillside along the hiking trail. It was probably hunting for the many Side-blotched Lizards that we saw skittering about nearby. These snakes are extremely fast, but we managed to get this little guy to calm down enough to pose for a few pictures.

Here's another cooperatively posing young striped racer. This one lacks the strong orange/red tint visible in the previous photos.
