Western Yellow-Billed Cuckoos.

Most of the remaining birds are found in isolated patches of riparian habitat along rivers in Arizona, California, and New Mexico. Surveys in California during 1986-1987 found only 30-33 pairs remaining in the state, compared with an estimated 15,000 pairs in the late 1800s.
