Amended recovery strategy for the chestnut-collared longspur (Calcarius ornatus) in Canada . : En3-4/261-2018E-PDF
"The Chestnut-collared Longspur (Calcarius ornatus) is a small ground-nesting songbird endemic to the Northern Great Plains of the United States and Canada. In Canada, the Chestnut-collared Longspur breeding population is found in grazed mixed-grass prairie parcels that are at least 39 ha in southeastern Alberta, southern Saskatchewan, and southwestern Manitoba. The Chestnut-collared Longspur was designated as Threatened in Canada by COSEWIC in 2009 because of long-term population declines. In 2012, the species was listed as Threatened under Canada’s Species at Risk Act (SARA). Recovery is considered feasible for this species. The population and distribution objectives for the Chestnut-collared Longspur include stabilizing the Canadian population trend and then increasing and maintaining the population size at or above the mean abundance levels found during the 1980–1989 time period throughout the longspur’s historic range in Canada. Broad strategies are recommended to achieve the above objectives and to address the threats to the survival and recovery of the species”--Executive summary, p. iv.
