Virginia Opossum Tracks

Virginia Opossums have extended their range far enough north that even in parts of northern New England they are present and remain active year-round.  Opossum tracks in the snow provide an opportunity to observe the unusual toe structure of these marsupials. 

Opossums have five toes on all four feet.  The toes on their front feet can spread wide apart, often resulting in a star-shaped track.  The inside toe of their hind foot, or “thumb,” is opposable, has no nail, and often points in the opposite direction of the other four toes.
