Habitat

Breeding Evidence Map

Bairdís Sparrows breed in grasslands in Southern Manitoba. Although once ranging as far east as Winnipeg and as far north as Swan River, they have undergone considerable range collapse in Manitoba and are now largely restricted to an area in the southwest bounded on the north by the Assiniboine River and on the east by Boissevain. From the first half of May to early October, Bairdís Sparrows can be observed mostly near Lyleton, Melita, and Pipestone. July is arguably the best month to find singing Bairdís Sparrows in Manitoba.

The species is usually found in grazed pastures (image f), but is also observed in haylands, "idle" grassland, and cropland, favouring lush, medium-height vegetation in ravines and other low-lying areas. Nonetheless, if grassland is not grazed or burnt for many years, idle grasslands may become too densely vegetated and shrubby to support Bairdís Sparrows. Bairdís Sparrows sometimes use croplands for foraging but not for nesting.

The nest is usually hidden in dead material at the base of a tuft of grass, but sometimes in a more open setting
