My trusty game camera is the perfect tool to use to identify whatever animal is responsible for this.
Foxes.
This was the area where a mama groundhog dug a burrow and raised a litter of three babies last year. A fox family appears to have moved into the empty den now and has set up housekeeping.
Having foxes in residence back there should keep the groundhog numbers in check, so we aren't overrun with them like last year.
Looks to me like one of these foxes in the photos is larger than the other(s). Perhaps it's a parent and kits? Whatever the situation, they are welcome. We don't have chickens, and neither do any of our neighbors. Based on the animal parts outside the den, it looks as if these foxes have mostly been scavenging, not hunting.
I will continue to monitor the area, to see what else may be back there. I'll let you know if I find something.
It's a beautiful day today ...
Happy Sunday, Everyone!
