The American Tree Sparrow is brown above with two white wing bars, and yellow below with a dark spot on the breast. It has a red brown cap, and a bill with the top darker and yellow below. Despite its name, it is not particularly associated with trees. It has a range of Alaska and Northern Canada, and resides the farthest North of any of its relatives. It has a habitat of arctic scrub, willow thickets, brushy roadsides, weedy edges, marshes, and feeders. It feeds mostly on seeds and insects. It often comes to feeders with Dark-Eyed Juncos.
