Cool Facts

* The Song Sparrow is found throughout most of North America, but different populations in different areas can look surprisingly different. Those found in the arid Southwest are lightly marked and pale while those in the Pacific Northwest are dark and heavily streaked. The sparrows found on the Aleutian Islands of Alaska are even darker, and are huge: one-third longer than the eastern birds, and weighing twice as much.

* The range of the Song Sparrow is nearly continuous from the Aleutians to the eastern United States. However, the species is also found on the plateau of central Mexico, about 1500 km (930 mi) from the next closest population. The Song Sparrows of central Mexico have white throats and chests with black streaks.
