||This chapter describes the impacts of fire on birds in the mixed-grass prairie, particularly research conducted in North Dakota. The response of killdeer, marbled godwit,upland sandpiper, willet, eastern kingbird, willow flycatcher, sedge wren, yellow warbler, common yellowthroat, bobolink, western meadowlark, red-winged blackbird, brown-headed cowbird, savannah sparrow, grasshopper sparrow, and Baird’s sparrow is discussed. Overall, the birds responded to fire in three ways. The first group responded positively to fire; these birds usually preferred open areas with short vegetation. A second group used habitats that needed some protection from fire. The third group avoided recently burned areas but preferred habitats that had little wood vegetation.
