Crisp facial markings make the White-throated Sparrow an attractive bird as well as a hopping, flying anatomy lesson. There’s the black eyestripe, the white crown and supercilium, the yellow lores, the white throat bordered by a black whisker, or malar stripe. They’re also a great entrée into the world of birdsong, with their pretty, wavering whistle of Oh-sweet-canada. These forest sparrows breed mostly across Canada, but they’re familiar winter birds across most of eastern and southern North America and California.
Backyard Tips
White-throated Sparrows readily visit feeders or peck at fallen seeds beneath them. They feed on millet as well as sunflower seeds. If you make a brush pile in your yard it will give White-throated Sparrows a place to take cover in between trips out into your yard to feed.
Cool Facts
- The White-throated Sparrow comes in two color forms: white-crowned and tan-crowned. The two forms are genetically determined, and they persist because individuals almost always mate with a bird of the opposite morph. Males of both color types prefer females with white stripes, but both kinds of females prefer tan-striped males. White-striped birds are more aggressive than tan-striped ones, and white-striped females may be able to out-compete their tan-striped sisters for tan-striped males.
- Although they look nothing alike and aren’t particularly closely related, the White-throated Sparrow and the Dark-eyed Junco occasionally mate and produce hybrids. The resulting offspring look like grayish, dully marked White-throated Sparrows with white outer tail feathers.
- White-throated Sparrows typically nest on or near the ground. Occasional nests are built up to 15 feet off the ground in conifers. Usually, these nests are second attempts after a pair has had a ground nest robbed by a predator.
- The oldest recorded White-throated Sparrow was at least 14 years, 11 months old, when it was recaptured and rereleased during banding operations in Alberta.
