|Cactus wren populations are declining in Southern California due to the destruction of cactus shrubs.|
Cactus wrens are fairly common in the desert, but numbers are declining in Southern California, because they rely on a very unique and rare habitat—cactus scrub. There are several small populations of coastal cactus wren in San Diego, Orange, Riverside, Los Angeles, and Ventura Counties, but they are becoming more isolated because of urbanization and habitat loss.
