The Yellow-billed Cuckoo (Coccyzus americanus americanus) is a large, long (26-30 cm [10-12 in]) bird that breeds across the US and in parts of southern Canada. The eastern subspecies east of the Rocky Mountains. In New Mexico, it is found east of the central mountain chain in lowland, deciduous woodlands; willow (Salix spp.) and alder thickets; and second-growth woods. It breeds in riparian woodlands and similar habitats. It eats insects, lizards, eggs, other birds, and berries. The eastern population of the Yellow-billed Cuckoo will experience a high degree of climate exposure and has a moderately low adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Moderately Vulnerable under the Representative Concentration Pathway (RCP) 4.5 Scenario and Extremely Vulnerable under the RCP 8.5 Scenario. The Yellow-billed Cuckoo’s climate change vulnerability is impacted by factors related to movement, ecological role, and abiotic niche, which influence its ability to shift in space and respond to climate change impacts.
