White-Crowned Sparrow or White-Throated Sparrow?

General appearance

The white-throated sparrow is about the size of a Robin or Sparrow, measuring 6-7 inches or 15-18 cm in length. The bird sports a distinctive white throat which contrasts against a dark bill. This sparrow has a variety of colors in its plumage; black, brown, gray, white, and yellow. A yellow spot in front of the bird's eye marks a unique physical trait. The bird's wings are broad and its tail shape varies from notched, rounded to square-tipped.

Male vs female

Both male and female white-throated sparrows exhibit two color morphs, namely white-striped and tan-striped. However, white-striped birds tend to pair off with tan-striped birds, suggesting some visual differences between the sexes which may not be readily discernible to the human eye.

Juvenile

Juvenile white-throated sparrows or 'first-winter' birds may not be as visually vibrant as their adult counterparts. They display a duller color palette with blurry streaks that appear below their bodies. As they age, they will develop the clear, contrasting color patterns distinctive of this species.

Primary habitat

The white-throated sparrow's preferred habitat is the undergrowth of conifer and mixed woodlands, mainly in openings with dense deciduous shrubs. This bird species breeds in zones of coniferous and mixed forest.

Additional range

In the winter, these sparrows can be found in areas with dense, low cover including forest undergrowth, edges, well-vegetated suburbs, parks, and even roadsides. They also inhabit areas around ponds and clearings.

Natural diet

The white-throated sparrow primarily consumes seeds and insects. During its breeding season, the bird's diet consists largely of insects such as damselflies, ants, wasps, true bugs, beetles, flies, caterpillars, spiders, millipedes, and snails. In winter, its diet shifts to focus on seeds, especially from weeds and grasses. It also consumes various berries, predominantly in the fall. Young birds are mostly fed insects to support their growth.

Bird feeders

The white-throated sparrow is known to visit bird feeders where it typically consumes seeds such as millet, cracked corn, and sunflower seeds. These foods mimic its natural winter diet and are appealing during times when insects are less available.
