Yellow-billed Cuckoo (Coccyzus americanus) Science Article 4
The future federal status of the Yellow-billed Cuckoo (Coccyzus americanus) in NorthAmerica remains unclear. A petition was filed in 1986 to list the western subspecies (C. a.occidentalis) under the Endangered Species Act (ESA). The U.S. Fish and Wildlife Service(USFWS) published a 12-month finding in 1998 stating that the petition was not warranted dueto the fact that the petitioned area did not encompass a distinct population segment.
