Mammals
Coyote
Canis latrans
- 9/26: Lucas Valley-Marinwood, CA. After spending the day at Abbott’s Lagoon, where several other folks reported seeing a coyote on the ridge – but I never managed to catch a glimpse – I was thrilled to find this gorgeous friend while driving home on Lucas Valley Road in the late afternoon. As we approached, I actually thought it was a fox: my impression was of a small canid leaping as if hunting some smaller prey. But as we got closer, I saw it was definitely a coyote. The animal wasn’t particularly happy about having been noticed by us, and it quickly turned and ran farther from the road.

- 9/26: Point Reyes, Marin County, CA. As we were returning to the Abbott’s Lagoon trailhead fairly late in the afternoon, it occurred to me that we hadn’t seen any deer all day long, which seemed strange. Then I looked over at the open grassland on the other side of the preserve fence, there they were: three or four deer, foraging as evening began to fall. While driving home, we swung by the Bear Valley visitor’s center trailhead, and there were several deer foraging there, as well.
