Section 7 Range

Under Section 7 of the Endangered Species Act of 1973, Federal agencies, or project proponents whose actions have a Federal nexus (e.g., Federal funding, permit, or lease), must consult with the U. S. Fish and Wildlife Service if their actions “may affect” listed species (endangered, threatened, proposed, candidate) or their habitat.  Section 7 species ranges identify those areas on the landscape where agencies or proponents should consider potential effects, both direct and indirect, to the species and their habitat.  These Section 7 species ranges typically encompass larger areas than specific locations where listed species are known to occur.  Project proponents are encouraged to refer to the Service’s Information, Planning, and Conservation System (IPAC) website at http://ecos.fws.gov/ipac/ or to contact the FWS Wyoming Ecological Services Office for additional information http://www.fws.gov/wyominges/ :307-772-2374.  (Section 7 Range boundaries based on the best available data at time of development.  Section 7 Ranges will be updated as new information becomes available.)

Species Information

The distinct population segment of the yellow-billed cuckoo (Coccyzus americanus) west of the Continental Divide is proposed for listing under the ESA as a threatened species (78 FR 61621; October 03, 2013).  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.
