On Quercus lobata
Larger than the Sylvilagus bachmanii I see more commonly in the SF Bay Area.
Both dark and light morphs were observed today. Dark morph in photo.
This eagle was on the road to Mercey Hot Springs. I saw another along Panoche Rd. in San Benito County that I'll list separately.
I saw these manzanita from Panoche Rd. The area is largely private property and fenced, so I could never get close enough to identify them.
