Guide to Boreal Birds
The plowing of the prairies reduced the habitat of the Clay-colored Sparrow, but with the clearing of forests it has extended its range northeastward and now breeds in the eastern Great Lakes region. Each spring and fall a few individuals, most of them immatures, appear on the Eastern Seaboard, where they can be difficult to distinguish from immature Chipping Sparrows, with which they often associate.
