Evidence of our prickly neighbour

Birch and pine are its favourites

A white birch with its bark gnawed away shows that a porcupine was here. Cork and I found this tree yesterday and the damage looks recent. I expect we will find more such trees in the future.
Porcupines do not travel far in the winter. When it gets really cold they seem to hibernate right on the tree. They don't move at all for days.
