It was dead just there on the path
This dude sat still for you to take pictures of him as you drove by. Evidently used to humans and expected food as a reward for his behavior.
Spotted along the bike path that runs along the back side of the park, fresh kill. Possible victim of coyote attack. Initially believed the reds avoided area due to density of coyote population in the surrounding areas,rarely seen. Middle of suburban neighborhood adjacent to Contra Loma Reservoir
Family of 5 foxes—seemed like 1 adult and 4 juveniles but possibly all juveniles
