California's foothills are blanketed with vast swaths of shrubbery, also known as chaparral. This dense growth provides habitat for a number of animals. Buck brush (Ceanothus cuneatus) is one of our dominant chaparral shrubs. It is eaten by caterpillars of the Ceanothus Silk Moth (Hyalophora euryalus). California Thrashers (Toxostoma redivivum) use their long, curved bills to dig for food in the leaf litter beneath shrubs and perch atop them to sing.
