Current status:

State endangered, candidate for federal endangered listing


Riparian forest, particularly large patches of dense cottonwood and willows.  Historically common in riparian areas of the Central Valley and southern California, it now breeds primarily in three locations in California: Sacramento Valley, Kern River, and Lower Colorado River

Cause of decline:

Loss of suitable riparian habitat due to conversion to agriculture, alteration of natural river processes, and development of human settlements

Current primary threats:

Habitat loss and fragmentation

What we’re doing about it:

Since 2010, Point Blue ecologists have been adding to previous knowledge about cuckoos by conducting surveys in riparian, or streamside, habitat along the Sacramento and Feather rivers to estimate population size and gather information about Yellow-billed Cuckoo habits and habitat preferences. These surveys have found a very small population and identified areas currently being used by cuckoos. We’re using this information to help land managers plan restorations in the Central Valley to help this species recover.
