Abstract:Climate change is having a disproportionate impact on the Arctic. For Arctic breeding birds, basic knowledge of their annual cycle, specifically the timing, route, and movement behavior of migration, is needed to understand when and where populations may experience threats. We used a combination of geolocators and stable isotope analysis to identify route and timing of migration in Smith's Longspurs (Calcarius pictus) that breed in Alaska's Brooks Range. We trapped males on their breeding grounds from 2011 to … Show more
