It's not turkey related, but is birds and reflection related. Some relatives had a second home, with mirrored windows. Whenever they arrived at this second home, sometime weeks between visits. They would find the windows all dirtied up and bloody, I mean A LOT of blood. It would take then the better part of a day, to clean up the mess. So some game cameras were set up to try and catch the culprit. On the next visit, they found the windows in bad shape again. This time, game cameras would tell the tale. It turned out to be a pair of Ravens, it appears they spent a considerable amount of time, fight off the fake intruders. The house was sold some while later, I would guess the current owner is still having this issue. It always happened in the spring, nesting and territorial dispute season.
