Cool Facts from www. birds. cornell. edu

The White-throated Sparrow comes in two color forms: white-crowned and tan-crowned. Tan-crowned birds have dull whitish or light tan head stripes, and more brownish chests that usually contain some streaking. In the spring when the sparrow is most brightly colored, most individuals are easily assigned to a color morph. In fall, the morphs are more similar and many birds appear intermediate between the two.

The two color forms of the White-throated Sparrow are determined by genetic differences, and are unique among birds. Oddly, 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 outcompete their tan-striped sisters for tan-striped males.

Although they look nothing alike, 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.
