MARQUETTE (AP) — A former state lawmaker from Marquette says he took a photo of an unusual deer: a buck with three antlers in the Upper Peninsula.

Steve Lindberg posted the photo to his Facebook page, where he regularly shares pictures from the outdoors.

A veterinarian, Steve Edwards of Lakeview, said the deer is normal and healthy. It’s possible that something happened when the deer was an embryo before birth, Edwards said. He told the Detroit Free Press that the three-antler deer is probably a “one-in-a-million thing.”

The traditional deer hunting season starts Friday.
