They occur in southwestern San Bernardino County in washed and lower slopes from Yucaipa including the Santa Ana River, Lytle, Cajon and Mill Creeks. They are scare due to habitat loss and degradation.

Their diet consists of mostly insects such as grasshoppers, ants, beetles and wasps, but they have also been known to eat vegetation and prickly-pear fruit. They are year-round residents and tend to have high site fidelity.
