The Lapland Longspur (Calcarius lapponicus alascensis) is a small, chunky bird (15-16 cm [6 in] long; 22-33.1 g [0.8-1.2 oz]) resembling a sparrow with a bold black, white, and chestnut head pattern in the breeding male and paler pattern of reddish brown above and white below in other birds. It eats seeds and also invertebrates in the breeding season and is found in open treeless habitats. It breeds in northern Canada and winters in the US. The Lapland Longspur 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 both Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 Scenarios. The Lapland Longspur’s climate change vulnerability is impacted by factors related to 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.
