Talk about a family tree! This bird has two dozen or more subspecies!

The Song Sparrow has 52 named subspecies, although there appear to be 24 that are truly identifiable. These subspecies vary widely in size, plumage color, and pattern, so if you travel to another part of the country, the Song Sparrows you see may look a bit different than the ones you are used to.

Other birds with many subspecies include the Fox Sparrow, Horned Lark, and Yellow Warbler.
