The American Tree Sparrow is a cold-weather sparrow that nests at the edge of the arctic tundra, in open areas with scattered trees and brush..   It is seen south of Canada in winter only, when flocks roam forest edges, brushy fields, groves of small trees and gardens, often with other sparrows and juncos.

They have a gray head and nape crowned with a  rusty cap, two-toned bill, dark chest spot and two white wing-bars.   Its song is musical clear whistles and warbles. 

They are high northern nesters, breeding from northern Alaska east to northern Labrador, but winter from southern Canada to nortern California, central Texas, and South Carolina.

Their song is a noticeably syncopated series of clear, whistled notes, often doubled or tripled and high-pitched at the beginning.
