Brown, gray and black chipmunk with black stripes on face and down the back.
Unknown bush in coastal scrub and Oak forest of Daley Ranch. It was about 1,300 feet / 396 meters in elevation.
I've been unable to locate a species recorded in this area but there are some nearby. "The only chipmunk that inhabits San Diego County is the Merriam's chipmunk. It is common and occurs widely from the inland valleys east to the western edge of the desert. Typical habitat is chaparral, oak woodland, and oak-pine woodland but I have observed them in desert transition habitat in the county." - Dept of Fish and Game
