Description
Unlike some other bird species, the american Tree Sparrow prefers building its nest on the ground close to tree lines or hedges. It also forages on the ground for seeds. Since it is a cold climate bird, it must consume around 30 percent of its body weight to survive the chilly temperatures. Placing a bird feeder in the backyard may bring the small, plump sparrow to the area.

Feeding Habits
American Tree Sparrow's diet shifts seasonally, consuming mainly seeds from grasses, sedges, and weeds like ragweed and goldenrod in colder months. They also eat berries and occasionally ground-scattered millet from feeders. During summer, their diet is insect-heavy, with a variety of beetles, flies, wasps, and caterpillars crucial for chick development, before returning to seed-based feeding.
Habitat
American Tree Sparrow's preferred habitats are varied across seasons. During breeding, they inhabit the northern treeline with alder, willow, birch, and spruce, transitioning to open tundra but often near water sources and sparse trees for perching. In migration, they frequent weedy fields, marshes, hedgerows, and forests. Winters find them in brushy roadsides, weedy edges, marshes, and even urban gardens and backyards with feeders. These habitats range from Arctic scrub to willow thickets, indicating american Tree Sparrow's adaptability to different environments, with preference for areas abundant in foraging opportunities.
Nest Behavior
American Tree Sparrow engages in nest-building typically on ground level and prefers the shelter of grass tussocks or shrub bases. Egg-laying follows nest construction, with parents demonstrating dedicated care to both eggs and hatched young during the breeding season.
Nest Characteristics
American Tree Sparrow's nest is an open cup built on or near the ground, commonly nestled in grass tussocks or at the base of a shrub and sometimes elevated on a willow or spruce branch. It is constructed from moss, grasses, bark shreds, twigs, and lined with fine grass and ptarmigan feathers.

Behavior
American Tree Sparrow typically engage in industrious foraging, often in flocks during winter, hopping in search of seeds, berries, and catkins. They exhibit adaptability, for instance, using their wings to knock seeds from snow-covered grass. Blizzards do not deter them; instead, they continue their quest for food. Come summer, their diet shifts to insects, sometimes catching them mid-flight. When spring arrives and migration begins, the flock's cohesion wanes and american Tree Sparrow form pairs. Females become nest-bound within the male's territory, while males stay nearby, vigilant and attentive to the nest. Post-breeding season, the pairings dissolve.
