Who was here?

For four weeks only small birds visited the snowy patch out back. Today we found signs of a visitor(s). But what variety? Vaguely paw-like marks but a creature of virtually no weight, and all prints seem to face forward, towards the mountain view. And yet so many tracks! We don't have rabbits here, or at least no previous evidence of them, such as nibbled lettuce. Tomorrow I will hunt for a good print among the dozens out there.
