Song Sparrow

Saw many of the usual birds at the park this afternoon, until along comes a bird foraging far off to the left and right of the main group. This is yet another type of sparrow, and I hope I've correctly identified it as a song sparrow. This bird lives year round in Illinois.

Didn't get to hear it's song, so played audio clips on the allaboutbirds.org site.  The song sparrow alarm call caused Nilla our dog to start barking.
