Vesper Sparrows are less common than Song Sparrows, but are similar with fairly heavy streaking on their flanks and breast (Vesper's streaks are not as thick). Also Vespers have less reddish coloring on their wings, crown and tail. Vesper's bills are not thick or gray as a Song Sparrow's, and Vespers have a complete eye-ring, which Song Sparrows lack. Also their songs a bit more buzzy than the Song Sparrow's.
