Size

These birds have a length of 6.5-7.5in (17-19 cm) and a weight of 28 g (1 oz). Their wings could range from 9.28-10.25 in (23-28 cm).

Feeding

The white-crowned sparrow eats 92% plant matter. This species’ small tough bill makes seeds, buds, grass, and fruit ideal food sources. In the spring, it changes its diet to include insects and seeds. This ground feeder relies on dense shrubbery to protect it from predators.

Habitat

The white-crowned sparrow has been shown to be a very adaptable species. From parking lots to Rocky Mountain meadows and boreal forests. Tall coniferous trees along a territory’s edge, grass and bare ground for foraging, and dense cover to conceal a nest or roosting area are all they need.

Behavior

The white-crowned sparrow is a lonesome bird. Males are fiercely territorial, despite migrating in a small group of eight. Most return year after year to guard non-overlapping established territories. In response to an intruder or predator, the male sings loudly, puffing up his chest. When a male first enters his territory, especially during the breeding season, he will fight often. This behavior, along with the specific territories that a male can guard, establishes a clear hierarchy within the species.
