Breeding Evidence

Chestnut-collared Longspurs are double-brooded with peak laying nears, near Winnipeg, from late May to early June and mid-July. Their song is quite similar to that of Western Meadowlark but much softer and can be a good way to detect these birds.

The nest is an open cup on the ground in low grasses (image to the left), sometimes partially concealed by a nearby clump of taller vegetation. As a general rule of thumb, Chestnut-collared Longpurs are found in large grassland areas with short grass and patches of open ground.

Habitat

Breeding Evidence Map

Like the Bairdís Sparrow and other grassland SAR, the Chestnut-collared Longspur has declined precipitously in Manitoba and their range has shrunk in this province. They are now only found in an area extending south and west of Carberry, northward along the Assiniboine River to St. Lazare. They are occasionally reported further north in remnant fescue prairie sites.

Breeding populations can be found in pockets:

  • near Lyleton and Pierson;
  • within the Souris River and "blind Souris" valleys south of Melita; and
  • on the "Poverty Plains" west of Melita.

Chestnut-collared Longspurs prefer unbroken prairie (images a, b, and c); but will nest in pastures.
