The White Crowned Sparrow is a year-round resident in the Pacific Northwest, with a range that spans from British Columbia, Canada, to northern California, USA.
They inhabit a variety of habitats, from urban gardens to rural woodlands, and from sea level to mountainous regions.
Their diet consists mainly of seeds, fruits, and insects, which they forage for on or near the ground.
These adaptable birds can be found in a range of elevations, from low-lying coastal areas to mountainous regions, where they thrive in forests, woodlands, and even backyards.

Habitat and Distribution
The white-crowned sparrow is a highly adaptable bird when it comes to its habitat. They can be found in a variety of environments, from the edge of parking lots to boreal forests.
Tall coniferous trees on the edge of a territory are a must-have for these birds. They also need grass and bare ground for foraging.
The white-crowned sparrow can breed in many different areas, including at altitudes as low as 800 meters. This flexibility is likely due to the ease of their habitat requirements.
In the spring and fall, white-crowned sparrows live in groups with other sparrow species. They forage and roost together during this time.
In the winter, the subspecies of Zonotrichia leucophrys that migrate remain in a steady group. This group dynamic likely helps them navigate the winter months.

Subspecies Comparison
Gambel's White-crowned Sparrows have pale lores and nest from the western side of Hudson Bay to Alaska.
These birds intergrade with dark-lored Eastern Taiga birds around the southern end of Hudson Bay into Quebec, resulting in a mixture of dark-lored, pale-lored, and intermediate nesting birds.
True Gambel's White-crowned Sparrows are extremely rare visitors to the northeast, based on band recoveries of White-crowned Sparrows coming from or going to Western Canada.
However, pale-lored birds from the variable and mixed populations east of Hudson Bay may be mistaken for true Gambel's birds, as they can be found in small numbers in northern Quebec.
Further field work is needed to determine the range of pale-lored birds and to look for any possible differences between these pale-lored Eastern birds and true Gambel's from the west.

Range and Habitat
The white-crowned sparrow is a highly adaptable bird that can thrive in a wide range of habitats. From the edge of parking lots to the meadows in the Rocky Mountains, they can be found in many different areas.
They require tall coniferous trees on the edge of a territory, grass, and bare ground for foraging, as well as dense coverage to hide a nest or roosting area. This flexibility allows them to breed in many different areas, including at altitudes as low as 800 meters.
In the spring and fall, white-crowned sparrows live in groups with other sparrow species, while in the winter, the subspecies that migrate remain in a steady group for foraging and roosting.
Crowned Sparrow
The Crowned Sparrow is a bird species found in a variety of habitats.
It's worth noting that they can be found in urban areas, particularly in parks and backyards.
They inhabit areas with dense vegetation and shrubs.
In some regions, they can be found in agricultural fields and orchards.
Their ability to adapt to different environments is a key factor in their success.
By exploiting food sources in these diverse habitats, the Crowned Sparrow is able to thrive.
Their diet consists of seeds, fruits, and insects.
In some cases, they have been known to visit bird feeders.
Habitat
The White-crowned Sparrow is incredibly adaptable when it comes to choosing a habitat.
They can be found in a wide range of environments, from the edge of parking lots to the meadows in the Rocky Mountains, and even in boreal forests.
The only features they require are tall coniferous trees on the edge of a territory, grass, and bare ground for foraging.
Their flexibility in habitat choice allows them to breed in many different areas, including at altitudes as low as 800 meters and as high as within the Rocky Mountains.
In the spring and fall, they live in groups with other sparrow species, while in the winter, the migratory subspecies remain in a steady group with which they forage and roost.
They can be spotted hopping on the ground or perching low inside bushes in many habitats, including weedy fields, thickets, city parks, suburban yards, alpine meadows, roadsides, and edges of woodlands.
The female White-crowned Sparrow builds the nest, using twigs, grasses, pine needles, moss, bark, and dead leaves, with finer grass and sometimes hair used to line their nests.
Nests are usually fairly low to the ground in thickets, not higher than 3-10 feet, but in far northern regions where brush or thickets are not available, they build nests on the ground, hidden behind clumps of moss or in other types of groundcover.
