Recovery strategy for the Chestnut-collared Longspur (Calcarius ornatus) in Canada . : En3-4/261-2017E-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. During the breeding season, males can be readily distinguished from females by their black and white plumage and chestnut patch on their nape. Females appear more sparrow-like and are greyish-buff overall with dusky stripes. Both sexes have dark inner, and white outer tail feathers that form a black triangle that is readily seen when the bird fans its tail. 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"--Executive Summary, p. iv.
