Near the railroad track lining Warner Park, depressions in the snow marked many paths -- coming, going and crossing. Some of the prints set close together, others further apart.
Most of the tracks belonged to two foxes, according to Madison resident Rhonda Martin.
Martin lives near Warner Park on Madison's north side, and sees the foxes so regularly she can keep track of their family trees. She can list the members of the family individually, noting when and how many babies (known as kits) each had, as if she knew them personally.
One female fox had two kits in 2011, one of which took over territory near the baseball field where the Madison Mallards play. He’s still there, Martin said. The other kit -- a female -- made a den down the railroad tracks from her mother, and had five kits of her own in 2013. She and four of her kits were run out of the territory by the fifth, a male.
