Last week I saw a North American porcupine (Erethizon dorsatum) next to and inside a burrow. In open areas (including grasslands) porcupines use and modify existing burrows made by other animals. I thought I would return with my camera a week later. However, there were only some quills and bones next to the burrow; the porcupine probably died at some point last week. A few hours later, just before dark, I noticed an American badger (Taxidea taxus). The animal was digging out a burrow of its own a few hundred meters from where the porcupine was eaten. My suspicion is that the badger killed and ate the porcupine, similar to Eurasian badgers and hedgehogs in Europe; badgers have powerful claws and can unroll hedgehogs and eat them starting at the belly...
