I had an encounter with a young porcupine yesterday. He didn’t see or hear me at first while he was munching on some newly-greened grass. (Sex assumed.) Porcupine eyesight is poor, but their senses of smell and hearing seem to be fairly keen. I was trying to be as quiet as possible and was lucky to be downwind when I came upon him.
I got closer and he finally sensed me. He bristled his rear quills to start the typical defensive posture.
He slowly turned away to complete the defensive posture: rear quills up and spread and turned toward the perceived threat, tail flexed to whip about like a spiked club.
I never felt threatened. Porcupines are slow thinkers and movers. In my many experiences with them, they have never attacked or even lunged aggressively. They rely on their short tails to affirmatively swipe at threats. Contrary to myth, they do not “shoot” out quills like darts. You’re usually safe if you don’t try to touch them and stay out of tail range.
Whether porcupines have outlived any positive evolutionary role is another story. We seem not to have enough fishers to keep the numbers of these tree- (and dog-) harming quilled cuties down. (Images taken in Brooklin, Maine, on April 5, 2025.)
