Tracks in Nature

In this nature challenge, show us examples of tracks, footprints, or indications of movement where an animal has been, (vertebrate or invertebrate). Your entry might show crab tracks in the wet sand, beetle tracks, snail trails, bird footprints, animal paw prints. I'll accept the deep rutted tracks made by animals such as sheep, goats, cows, etc as they persistently use the same pathways to food, water, shelter etc. Please, no tracks of domestic pets or human footprints, (too easy). Macro and close-ups welcome. Size of entry: 1,600px on its longer side.
