The American Tree Sparrow (Spizelloides arborea) is native to North America. Its geographical distribution spans across the northern and central regions of Canada and Alaska during the breeding season. In the non-breeding season, the species migrates to the central and southern United States.

The American Tree Sparrow's typical breeding habitat consists of open tundra and shrubby areas in the far north. These regions are characterized by cold temperatures, short summer seasons, and sparse vegetation. During the non-breeding season, it inhabits open fields, grasslands, marshes, and areas with scattered shrubs, which provide a milder climate with moderate temperatures.

The American Tree Sparrow occupies the ecological niche of a ground-foraging omnivore. It primarily feeds on seeds and insects, adapting its diet according to the availability of food resources in different seasons. The species plays a role in controlling insect populations and seed dispersal within its habitats.
