Native to North American prairies, chestnut-collared longspurs, migrate annually between breeding and wintering grounds. Breeding grounds are located east of the Rocky Mountains in the Canadian Prairies (from Southeast Alberta to Southwest Manitoba) and Great Plains of the United States (Montana, North Dakota, and South Dakota). Breeding areas are also found in eastern Wyoming and northeast Colorado, as well as in northwest Nebraska and western Minnesota, where populations have been greatly reduced. Chestnut-collared longspurs arrive at breeding grounds from March through May, and depart from mid-September through early-October. These birds winter from October through December in the southwestern United States and northern Mexico, departing from February through April. The typical wintering range extends from eastern Arizona to central Kansas, then south through northwest Texas and northern Mexico.
