Baird's sparrow (Centronyx bairdii) is a species of North American birds in the family Passerellidae of order Passeriformes.

The Baird's sparrow was first described in North Dakota in 1843 by John James Audubon, and another record of this species was not made for 29 years following its discovery.

[3] The Baird's sparrow migrates from its summer breeding habitat, the tall grass prairies of north central United States and South Central Canada, to spend winters in northern Mexico and the southern tip of the United States near Texas.

Fragmentation can lead to adverse conditions for Baird's sparrows, including increased nest parasitism.

This is most likely the result of a variable environment including factors like wildfires, drought, and the movement of American bison herds.

[2] When confronted with danger or a potential predator, Baird's sparrows may evade their foes by running on foot rather than flying away.
