The Field Sparrow’s trilling song is a common summer sound, and this pretty little bird is often heard before it is seen. Patient observers can track the song to its source: a small, pink-billed sparrow with a bold white eye ring, often skulking in a thick shrub or small tree. These particular field marks distinguish it from other small sparrows that may share its habitat, such as the Chipping Sparrow.
Other Field Sparrow characteristics include an unstreaked pale-gray chest and face, a rusty-brown streak behind the eye, and a reddish cap. Juveniles have narrow dusky streaking on the chest, sides, and crown. The sexes look alike.
