And as the Baird's sparrow moves deeper into Canada's prairie provinces, there will, in turn, be "unforeseen impacts on those natural communities.
Of the five open-grassland specialists in our study, only Baird's sparrow showed a negative association with shrub density; this is consistent with what has been reported for this species during the breeding season (Green et al.
However, Baird's sparrow, also a solitary forager, showed the opposite (negative) association with vertical grass density than that suggested and indicated by literature on responses to grass cover and height of grass in the nonbreeding season (Desmond et al.
Sprague's pipit, grasshopper sparrow, and Baird's sparrow are of international or regional concern for conservation (United States Fish and Wildlife Service, 2008; Berlanga et al.

We employed a flush mist-netting protocol (Gordon, 2000a) to sample savannah sparrows (Passerculus sandwichensis), grasshopper sparrows (Ammodramus savannarum), and Baird's sparrows (A.

For example, Baird's Sparrows require vegetation that is moderate to tall in stature, sparse to moderately dense, with moderate forb cover, sparse to moderate litter, and low amounts of woody vegetation.
Baird's Sparrows (Ammodramus bairdii), Grasshopper Sparrows (Ammodramus savannarum), Le Conte's Sparrows (Ammodramus leconteii), Sprague's Pipits (Anthus spragueii), Western Meadowlarks (Sturnella neglecta), and Bobolinks (Dolichonyx oryzivorus) were absent from unburned areas.
Occurrence of Baird's Sparrows was positively associated with frequency of native grasses.
