White-throated Sparrow

The White-throated Sparrow is a large, handsome sparrow of eastern and northern North America, easily recognized by its sharply defined white throat patch and small bright yellow spot between the eye and bill (the lores). It occurs in two color morphs regardless of sex: a white-striped morph with bold black-and-white head stripes, and a tan-striped morph with duller brown-and-tan head stripes; both morphs share the white throat and yellow lores.

This species is a common winter and migratory visitor to yards and woodland edges across much of the eastern and central United States, and it breeds in boreal and mixed forests of Canada and the northern U.S.

Key Field Marks

• Crisp white throat patch bordered by a dark malar stripe
• Small bright yellow spot (lores) between the eye and bill
• Bold head stripes, either black-and-white or tan-and-brown depending on morph
• Grayish breast and unstreaked belly (in adults)

Similar Species

• White-crowned Sparrow: lacks the white throat patch and yellow lores, has a plain gray breast and a pink or yellowish bill, and bold black-and-white crown stripes reaching the bill.
• Song Sparrow: heavily streaked breast with a central spot, unlike the White-throated Sparrow's plain gray breast.
• Fox Sparrow: larger, often more reddish, with heavy chevron streaking on the underparts and no yellow lores.

Habitat

They favor brushy edges, thickets, and dense understory in and near forests, including woodland edges, overgrown fields, and shrubby gardens, especially during migration and winter.

Range

White-throated Sparrows breed across the boreal forest of Canada and the northeastern and north-central United States, and winter across the eastern and southern United States, generally avoiding the far north in winter.

Migration

They are medium- to long-distance migrants, moving between northern breeding grounds and wintering areas farther south, often arriving at feeders in flocks during fall and remaining through winter.

Behavior

White-throated Sparrows often forage on the ground in flocks, scratching through leaf litter with a distinctive double-footed backward hop, and frequently associate with Dark-eyed Juncos in winter.

Voice

The song is a series of clear, thin whistles often rendered as "Oh-sweet-Canada-Canada-Canada" or "Old-Sam-Peabody-Peabody-Peabody," one of the most recognizable songs among North American sparrows.

Feeding

They eat seeds, berries, and insects, foraging mostly on or near the ground in leaf litter and low vegetation, and readily visit feeders offering millet or sunflower seed.

Nesting & Breeding

Nests are built on or near the ground in dense vegetation within boreal and mixed forest habitat, typically containing 3-5 eggs. Interestingly, the white-striped and tan-striped morphs almost always pair with the opposite morph, an unusual mating system tied to differences in behavior and hormones between morphs.
