The Baird's Sparrow, Ammodramus bairdii, is a small sparrow.
These birds have a large bill, a large flat head and a short forked tail. They have brown upperparts and white underparts, with streaking on the back, breast and flanks. The face, nape and crown stripe are yellowish.
They forage on the ground, mainly eating insects in summer and seeds in winter.
These birds usually nest in small loose colonies. Males sing from perches within their nesting territory. The song consists of a short series of high notes followed by a trill. This bird is more often seen than heard.
This bird's numbers have decreased with the loss of suitable habitat.
