Winter tracks

 A decent layer of snow reveals who is walking around the fields and woodlands.

First a view over the hills of Somerset after the fresh snow fall.

A medium-sized bird; perhaps a black bird.

A much larger bird - a pheasant.

Here some human 'tracks' - sledge marks on the hillside.

And finally the hoof prints of a very small deer. The shape is not distinct but there is little else that could make these regular marks.
