White-footed Mouse Tracks (Peromyscus leucopus)

mouse tracks in the snow.

Winter is a great time to go searching for mammals because the blanket of snow reveals evidence of their passage. These tracks were left by a White-footed Mouse (Peromyscus leucopus). If you look more closely, you might find discarded black cherry pits, caches of stored food, or burrows under tree roots also left by this species.

Although mammals are very secretive, it is possible to discover which mammals are present in an area.  If you have a good eye for details and have enough patience, you will soon find what you are looking for.  Look closely at the tracks, making notes on the details.  Some key characteristics that help in identification of mammal tracks include the number of toes on the front and hind print, the length of each print, the distance between paces or leaps, the pattern of the prints on the ground, and the presence or absence of tail mark or claw marks.  There are many field guides for identifying mammals from there tracks, both in snow and in mud.
