The coastal Cactus Wren (Campylorhynchus brunneicapillus) is found only in southern California. These birds have bold marking and harsh rasping call. They feed mostly on insects, some fruits, and seeds. This includes berries and cactus fruits. 
 

This is one of 32 sensitive species covered in our habitat conservation plan, and one of 12 birds on the list “covered species” list. Coastal Cactus Wrens populations have diminished in both size and distribution. This is primarily due to fragmented habitat loss of cactus scrub. On The Nature Reserve, these birds and their populations are scientifically monitored. Additionally, much care is taken to preserve and maintain cactus scrub habitats
