White-Crowned Sparrow or House Sparrow?

General appearance

The white-crowned sparrow has a striking black-and-white striped crown, gray face, and a pink bill. Its back is streaked brown, and its underparts are grayish. Its wings have two white bars.

Male vs female

Males and females are similar in appearance, both displaying the distinctive black-and-white crown pattern. However, males may exhibit slightly brighter plumage during the breeding season.

Juvenile

Juvenile white-crowned sparrows have a rusty brown crown compared to the black-and-white stripes of adults. Their overall plumage is browner and less distinctly marked, lacking the bright contrast seen in mature birds.

Primary habitat

The white-crowned sparrow primarily frequents boreal scrub, forest edges, thickets, chaparral, gardens, and parks. Their breeding habitats are consistently brushy, ranging from dwarf willow thickets at the edge of tundra to scrub just below mountain timberlines and along the Pacific Coast.

Additional range

In winter, the sparrow expands its range to include farms and desert washes. Such environments may be unexpected, but they are typically marked by the presence of hedgerows, overgrown fields, and desert washes.

Natural diet

The white-crowned sparrow's natural diet primarily consists of seeds, especially in winter, mainly from weeds and grasses. Throughout different seasons, it consumes various other vegetable matter, including buds, flowers, moss capsules, willow catkins, berries, and small fruits. Insects and spiders form an essential part of its diet, particularly in summer, and young sparrows are predominantly fed insects.

Bird feeders

White-crowned sparrows may visit bird feeders for seeds such as sunflower seeds, millet, and cracked corn. These common feeder offerings provide a supplemental food source especially during colder months when natural sources are less abundant.
