The Effects of Management Practices on Grassland Birds—Chestnut-Collared Longspur (Calcarius ornatus)

Professional Paper 1842-X
By: , and 



Keys to Chestnut-collared Longspur (Calcarius ornatus) management are providing and maintaining native pastures with fairly short overall vegetation and sparse litter accumulation but with areas of taller and denser vegetation and accumulated litter for nesting, and tailoring grazing intensity to local conditions. Chestnut-collared Longspurs have been reported to use habitats with 10–77 centimeters (cm) average vegetation height, 1–50 cm visual obstruction reading, 15–67 percent grass cover, 5–16 percent forb cover, less than (<) 6 percent shrub cover, 1–44 percent bare ground, 6–63 percent litter cover, and <7 cm litter depth.
