Bunting It

I give up. I looked through a bunch of sparrows, finches, bobolinks and Buntings, all with those little squat conical beaks. Frankly, they are all starting to look the same. If you're a bird person, let me know what this little guy is. Until then, I'm calling it a Bunting for lack of a better excuse. The little yellow patch on the forehead should be a clue but ironically, none of the birds had quite that coloration. So I give up. Hints and name donations will be graciously accepted.
