Baird's sparrow (Centronyx bairdii ) is a species of North American birds in the family Passerellidae of order Passeriformes. It is a migratory bird native to the United States, Canada, and Mexico.
The Baird's sparrow was named after the American naturalist Spencer Fullerton Baird.

B
starts withThe Baird's sparrow can be identified as a small brown streaked sparrow. Their faces are a yellow-brown color featuring subtle black markings. These birds have a narrow band of brown streaks on their chests. This species can be distinguished from others by its unique broad ochre central crown stripe. Juveniles exhibit similar coloration but often have more streaking. Adult size is comparable for both males and females, no sexual dimorphism is exhibited. Adults are generally about 12 cm (5") and weigh 17-21 g (½ to ¾ oz); their wingspan is usually around 23 cm (9").
They are larger than Le Conte's sparrow and do not exhibit orange coloration on their faces. They exhibit very similar coloration and patterning to Henslow's sparrow but do not have green coloration on their faces. The Savannah sparrow is more heavily streaked and has an extra white marking on its head.
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. Due to this migratory behavior, they may be spotted all across the Midwest portion of the United States during migratory seasons, but most frequently can be found in North Dakota, South Dakota, Minnesota, Montana, and Canada during the summer.
This species of sparrow resides in grassland habitats. These birds rely on the (now diminishing) tallgrass prairies, mixed grass prairies, and moister fescue prairies of northern United States and southern Canada. The dwindling status of this habitat puts many animals whose lifestyles rely on these ecosystems in peril. Land featuring woody vegetation and cultivated land is generally not a suitable environment for Baird's sparrows to thrive in.
There is some concern about the conservation status of Baird's sparrows; their numbers are reduced compared to historic numbers. This species is listed under the IUCN Red List under the category of "least concern". Maintaining the original habitat is important for this species because artificial habitat recreation is not suitable for these birds. Fragmentation can lead to adverse conditions for Baird's sparrows, including increased nest parasitism.
