Porcupine Calling Cards

    Porcupine(s) removed the outer bark of this healthy maple tree in order to eat the inner bark.
    Porcupine quills shed on bark chips surrounding a partially debarked maple tree.

    A bright orange spot in the drab, post-autumn woods caught my eye. It seemed to be fresh tree damage.

    Moving closer, I discovered that it was a large, healthy maple. But the bark was peeled from the root level to about two-and-a-half feet high. Only the bark was peeled, no gouges – the work of an expert.

    A thick layer of small bark chips surrounded the tree.

    Leaning in for a better look, grey and white quills stood out against the rich browns and oranges of the chipped bark ground cover.

    Porcupine!

    I scanned the trees in an unsuccessful attempt to spot one.

    Back at home, I looked at the Wisconsin DNR website to find out more about porcupines:

    • Winter diet – bark of pines, hemlock, maples and birch; needles and buds of pines.
    • Where to find porcupines in the winter – near small piles of freshly-snipped branches; in caves and hollow logs; in an area with fecal piles and/or smelling of concentrated urine.
    • They travel the same paths daily.
    • The fisher is the porcupine’s only significant predator.
    • The mostly silent porcupine sounds like a cross between a piglet and a crying baby.
    • And from a Northern State University site (South Dakota):
      • They don’t hibernate, they eat at night, and smell strongly of old sawdust due to their diet.
