sångsparv Melospiza melodia

One of the most common and widespread sparrows in North America. Fairly large with a long, rounded tail. Overall coarsely patterned with gray and brown, usually with more reddish-brown wings and tail. Look especially for thick brown streaks on the underparts and a broad dark mustache stripe. Significant variation in plumage geographically: relatively pale and rusty in the southwestern U.S.; blacker streaking in California; overall dusky in the Pacific Northwest. Larger, longer-tailed and usually more rusty than Savannah Sparrow. Found in a variety of scrubby habitats both near and far from human development, especially edges of fields, often near water. Listen for husky "chimp" calls and melodic song with chips and trills.
