Species Information
The distinct population segment of the yellow-billed cuckoo (Coccyzus americanus) west of the Continental Divide is a candidate for listing under the Act (66 FR 143; July 25, 2001). In Wyoming, the yellow-billed cuckoo is dependent on large areas of woody, riparian vegetation that combine a dense shrubby understory for nesting and a cottonwood overstory for foraging. Destruction, degradation, and fragmentation of wooded, riparian habitats are continuing threats to yellow-billed cuckoos in Wyoming. Additionally, project actions to control outbreaks of caterpillars, cicadas, or grasshoppers and the general use of insecticides in or adjacent to riparian areas may negatively affect yellow-billed cuckoos. Surveys to determine the presence of yellow-billed cuckoos are difficult due to the secretive nature of the species and the variability in the timing of nesting. Therefore, we recommend that projects avoid impacting large, woody riparian areas from late May to September, during the period when yellow-billed cuckoos seasonally occur in Wyoming. To help us better understand the distribution and status of the species in Wyoming, we request that all sightings of yellow-billed cuckoos west of the Continental Divide be reported to our office.
