Tiny footprints in the snow

Something was out prowling around recently in the snow in the woods behind our office. I'm no tracker but it looks like a two legged animal to me. Maybe a small bird. Or a fairy! Notice the sharp turn to the left and then another turn to the right (click on the photo to see it larger). At first I thought something might have startled it but it probably wouldn't have resumed its direction so quickly if it was afraid of something on its right. And there didn't seem to be a wider spacing of the prints after the turn as there would have been if it sped up. Just another mystery.
