A smallish sparrow at breeds in arctic tundra and migrates south to winter in the southern provinces and United States. Winters annually in southern B.C. but is fairly rare in most locations. Males and females look alike. Feeds mainly on seeds and insects. An individual was observed successfully flycatching for a flying insect (G. Gadsden, 2012). Earliest fall migration records are in middle October.

All sparrows can be tricky to identify. A lack of streaks on the breast of an American Tree Sparrow can help eliminate many of our common sparrows. Might suggest a juvenile White-crowned Sparrow but note facial pattern, bi-coloured bill, more prominant white wing-bars, black spot on breast and smaller size. Also most similar in appearance to a breeding plumaged Chipping Sparrow. However, most Chipping Sparrows are gone south by middle September and any that are left will be in duller nonbreeding colours (but are still distressingly similar). Compare the facial pattern and crown. See photos and video below.
