Conservation DecliningChestnut-collared Longspur declined by over 4% per year between 1966 and 2015, resulting in a cumulative loss of 82%, according to the North American Breeding Bird Survey. Numbers have fallen in every part of the species' range. Partners in Flight estimates a global breeding population of 3 million, with 78% spending at least part of the year in the U.S., 22% breeding in Canada, and 35% wintering in Mexico. This is a U.S.-Canada Stewardship species and a Tri-National Concern species. It rates a 15 out of 20 on the Continental Concern Score Chestnut-collard Longspur is on the 2016 State of North America's Birds' Watch List, which includes bird species that are most at risk of extinction without significant conservation actions to reverse declines and reduce threats.Back to top
