Image of North American porcupine

Description:

No animal photo here, but an interesting observation from a porcupine we captured to radio-collar. While recovering from anesthesia, it urinated (fairly common) and its urine was a deep orange/red color, seen in the photos. This was the first time I had seen that. Also shown are some photos of fresh feeding sign I took the same day, showing porcupine feeding on bark and needles of shore pine (Pinus contorta contorta) this time of year.
