They can, but they don't gain altitude so good. I had one fly across the road at top-of-windshield level. Since I figured it would just clear or just glance off, I did nothing to avoid it.

Unfortunately, I had a roof rack on. Fortunately, I was able to find replacement parts for the rack on eBay.

The turkey didn't appear to be harmed. After tumbling ass over teakettle to the ground, it walked into the field on the side of the road looking for all the world like a cat that wanted you to forget you'd just seen it do something beneath its dignity.

like wet sacks of cement...

Loved WKRP in Cincinnati. Always looked forward to the hog report. Not only can turkeys fly they bounce, too. A lot of unknowns, at the time, made appearances on that show before becoming famous themselves.
