Bent Life History for the Chestnut-collared Longspur - the common name and sub-species reflect the nomenclature in use at the time the description was written.

The Chestnut-collared Longspur is currently rated as Near Threatened. This bird prefers the north central region of the United States and central Canada. The Chestnut-collared Longspur migrates to Mexico and southern portions of the United States during winter. The Chestnut-collared Longspur tends to travel in flocks. The primary reason that this bird is currently rated as Near Threatened is loss of habitat, which has become fairly common with many prairie birds. More

The male Chestnut-collared Longspur defends his territory by performing Aerial Song Displays—flying upward to a height of 10 to 15 meters, then spreading his tail and singing during descent. Male plumage is conspicuous with black belly and cap, deep chestnut collar, and yellow cheek; the buff-colored female, by contrast, blends cryptically into its prairie habitat. Double-brooded and socially monogamous, this is one of many species in which extra-pair copulations occur; most extra-pair young are found in second brood nests. More

The upland prairies favored by the Chestnut-collared Longspur for nesting have been extensively planted in wheat, so these birds are much less numerous than in the past. They need only a small area, however, and often several pairs will crowd into a patch of land or even the narrow strips of unplowed grassland along highways. Here the males can be seen singing from the tops of fence posts, rocks or tall weed stalks. More

Appearance: The breeding male Chestnut-collared Longspur can be mistaken for no other bird: the breast and belly are entirely black, and the face is buffy yellow with a pale throat, white eye-line and black crown. The nape (or collar) is a rich chestnut. Females are quite drab and sparrow-like, pale brown overall, and easily concealed in prairie grasses. In flight, both genders show a distinctive tail pattern, with a black central triangle bordered by white outer tail feathers. More

Chestnut-collared Longspurs have been greatly reduced, particularly throughout the drift plains, and to a lesser extent elsewhere. Breeding Habitat. The optimum and more extensive breeding habitats in North Dakota are represented by tracts of grazed or hayed mixed-grass prairie (or mixed-grass-short-grass prairie ecotone) that are dominated by a mixture of species including blue grama, prairie junegrass, needle-and-thread, western wheatgrass, needleleaf sedge, and fringed sage.

The Chestnut-collared Longspur (Calcarius ornatus) is a breeding species of the prairie grasslands from north-central Colorado northward through much of Wyoming, the Dakotas and Montana as well as parts of south-central Canada. The species winters, sometimes in huge flocks, in the south-central United States. The territorial male birds in the next batch of images on the left were photographed at the Pawnee National Grasslands, Weld Co. More
