White-crowned Sparrow

Overview

The White-crowned Sparrow is a handsome, clean-looking sparrow best known for its bold black-and-white striped crown and plain gray face and breast. Unlike many streaked sparrows, its underside is unmarked, making the crown pattern the standout feature.

It breeds in far northern and mountain shrub habitats and is a familiar winter and migration visitor to backyards and brushy edges across much of the United States.

Recognizing the Feathers

• Crown feathers: bold, crisp black-and-white stripes running front to back (duller brown-and-gray in juveniles)
• Face/breast feathers: plain clean gray, unstreaked - a key difference from most other sparrows
• Back feathers: brown, streaked with black
• Bill: pink to yellowish-orange, a useful context clue when the bird is seen alive

The unstreaked plain gray breast combined with a bold striped crown is diagnostic; this separates it from the White-throated Sparrow (which has a white throat patch and yellow lores) and from heavily breast-streaked sparrows like the Song Sparrow.

Plumage

Adults show a bold black-and-white striped crown, plain gray face and breast, and a brown-streaked back. Juveniles show a duller brown-and-buff striped crown pattern instead of crisp black-and-white, gradually acquiring the adult head pattern. One complete molt occurs after breeding.

Habitat & Range

White-crowned Sparrows breed in shrubby tundra, subalpine, and mountain habitats across the northern reaches of North America and the western mountains, wintering widely across the southern and western United States and Mexico in brushy edges, gardens, and open scrub. Most populations are long-distance migrants.

Behavior & Field Notes

This sparrow forages on the ground for seeds and insects, often flicking leaf litter aside, and is frequently seen in small flocks during migration and winter. Its song is a clear series of whistles and buzzy trills, with regional dialects that vary geographically. A boldly crown-striped feather paired with a plain, unstreaked gray breast feather is a good White-crowned Sparrow indicator.
