Track Guide

This guide initially displays common tracks of all shapes. Use the selectors below to view particular shapes, include rare species, or search by name.

Anything that moves over the ground leaves some sort of marking of its passage. In particular, footprints left behind in soil, snow, mud, or other ground surfaces provide a means of recognizing different species. The illustrations and characteristics listed below highlight key features that can be used to identify the tracks of many of the animals in the area.

Porcupine

(Erethizon dorsatum)

Family: Erethizontinae (New World Porcupines)

Gait: walk
Form: small claws; round toes

Front Foot: 4 toes; 1.0 in (2.5 cm) - 2.1 in (5.3 cm)
Hind Foot: 5 toes; 1.4 in (3.6 cm) - 3.0 in (7.6 cm)

The soles of feet have small nubs giving prints a rough texture. Toes often do not register.

Winter scat is red from conifers; summer scat is brown to black from a diet that includes more herbs and scrubs. Either form may be composed of individual pellets or strings of pellets joined by fibers. Another sign of porcupine activity is bark chewed off of trees.
