Baird's sparrow (''Ammodramus bairdii'') is a species of North American birds in the family Emberizidae of order Passeriformes. It is a migratory bird native the United States, Canada, and Mexico. ==Description== The 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 and weigh 17-21 g; their wingspan is usually around 23 cm. 〔 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. 〔
