The Thick-billed Longspur (Rhynchophanes mccownii) is a small (14-16 cm [5.5-6 in]), sparrow-like songbird that is found in central North America, from southern Alberta and Saskatchewan south to northern Mexico. It is a migrant or winters south of Wyoming. It prefers habitat that has sparse, short grass or bare ground. It often nests in scrapes on the ground. Nest predation is a big mortality factor for this species. The Thick-billed Longspur, formerly known as the McCown’s Longspur, will experience a high degree of climate exposure and has a high adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Moderately Vulnerable under both Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 Scenarios. The Thick-billed Longspur’s climate change vulnerability is impacted by factors related to movement, life history, and evolutionary potential, which influence its ability to shift in space, persist in place, and respond to climate change impacts.
