The Vesper Sparrow (Pooecetes gramineus) is a small (13-16 cm [5-6 in]) sparrow that is found across mountain meadows, grassy mesas, and sagebrush steppe in the western US, the southern provinces of Canada, and the northern states of Mexico. It nests on the ground and is threatened by some agricultural practices and the loss of grasslands. The Vesper Sparrow will experience a high degree of climate exposure and has a high adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Less Vulnerable under both Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 Scenarios. The Vesper Sparrow’s climate change vulnerability is impacted by factors related to movement and life history, which influence its ability to shift in space and persist in place. It also has documented or modeled responses to climate change that impact its vulnerability score.
