The Clark’s Nutcracker (Nucifraga columbiana) is a large (28 cm [11 in]) songbird that is found from central British Columbia to southern New Mexico. It is mainly found at altitudes of 914-3,932 m (2,999-12,900 ft). Its primary food source is pine (Pinus spp.) seeds, which it also caches for winter. The Clark’s Nutcracker will experience a high degree of climate exposure and has a moderately high adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Moderately Vulnerable under the Representative Concentration Pathway (RCP) 4.5 Scenario and Highly Vulnerable under the RCP 8.5 Scenario. The Clark’s Nutcracker’s climate change vulnerability is impacted by factors related to distribution, movement, life history, and abiotic niche, which influence its ability to shift in space, persist in place, and respond to climate change impacts. It also has documented or modeled responses to climate change that impact its vulnerability score.
