Red Squirrel Sign

4-11-17 squirrel nip twig2 019An obvious sign of Red Squirrels, especially noticeable if snow is still on the ground, is the remains of their feeding activity. In winter and early spring, when snow may make finding food on the forest floor difficult, Red Squirrels show a preference for conifer buds. Rather than scurrying up a tree and eating the buds, they first prune the branch tip from the tree, eat the buds and then discard the tip onto the ground. Spruces, hemlocks and firs are some of their main sources of buds. If the squirrel feeds for a significant amount of time, the forest floor under the conifer it is feeding in can become littered with branch tips. Nip twigs scattered on the ground beneath hemlocks are also a sign of Porcupine feeding, but the tips they drop are much longer than the 2- to 4-inch tips discarded by Red Squirrels.
