The Yellow-billed Cuckoo is a state endangered species in California with breeding populations along the Sacramento River, Kern River, and Lower Colorado River. In 2010, from mid June until mid August, we conducted an extensive survey of the riparian habitat preferred by the cuckoo along the Sacramento River from Red Bluff to Colusa. We located 18 individual cuckoos using call playback surveys, spanning the entire study region. We performed an occupancy analysis using a range of territory sizes (15-75 ha) because territory size is not known for this population. Occupancy estimates predict that approximately 38 territories were occupied, depending on the size of territories. A population estimate derived from the occupancy estimate would be 38-76 cuckoos since each territory could be occupied by an individual or a pair. We did not find any significant relationships between cuckoo presence and various vegetation structure and composition measures. We believe that the Yellow-billed Cuckoo population has declined in the Sacramento Valley since the last survey during 2000, which is a cause for conservation concern for this important breeding area. Restoration of riparian habitat and further monitoring and research are needed to assist the recovery of the Sacramento Valley breeding population.90528:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=90528Tue, 24 Feb 2015 16:48:14 -08002011-02-14T00:00:00Cuckoo survey project data files - cuckoo surveys, vegetation surveys, monitoring, notes,GIS habitat patches layer, Sensitive species, metadata, help files90523:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=90523Tue, 24 Feb 2015 16:48:06 -08002014-01-01T00:00:00Status of Western Yellow-billed Cuckoo along the Sacramento and Feather rivers - To evaluate the current status of the western population of the Yellow-billed Cuckoo (Coccyzus americanus) along the Sacramento and Feather rivers in California’s Sacramento Valley, we conducted extensive playback surveys in 2012 and 2013. We also quantified the amount and distribution of potential habitat. Our survey transects were randomly located and spatially balanced to sample representative areas of the potential habitat. We estimated that the total area of potential habitat was 8,134 ha along the Sacramento River and 2,052 ha along the Feather River, for a total of 10,186 ha. Large-scale restoration efforts have created potential habitat along both of these rivers. Despite this increase in the amount of habitat, the number of cuckoos we detected was extremely low. There were 8 detection occasions in 2012 and 10 occasions in 2013 on the Sacramento River, in both restored and remnant habitat. We had no detections on the Feather River in either year. We compared our results to 10 historic studies from as far back as 1972 and found that the Yellow-billed Cuckoo had unprecedentedly low numbers in 2010, 2012, and 2013. The current limiting factor for the Yellow-billed Cuckoo in the Sacramento Valley is likely not the amount of appropriate vegetation, as restoration has created more habitat over the last 30 years. Reasons for the cuckoo decline on the Sacramento and Feather rivers are unclear.90522:3https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=90522Tue, 24 Feb 2015 16:47:57 -08002014-01-01T00:00:00
