Song Sparrow Concert
As you might expect, Song Sparrows like to sing, and I like the way they rear their heads back when they're in "concert mode". For (relatively) small birds, they really can belt out a tune.
There have been 52 recognized subspecies, but currently ornithologists agree on 25 subspecies. While a widespread species like the Song Sparrow can be expected to have some variations, 25 is a pretty high number of subspecies. Most of these differences appear to be superficial visual variations though, without all that much genetic diversity. It's unlikely that any of them will be spun off into separate species unless taxonomists radically change the species/subspecies requirements.
