I had a feeder I kept feeding year round. One trip I filled it and sat in stand for a few hours. Noticed what turned out to be a 5 footer under it. It would wait for and eat the birds that were coming to the corn. I was at a safe distance so I wasn't threatened. I picked up a baseball sized flat rock and flinged it side armed. Thawack. Broke its neck. Couldn't make that throw again I my life depended on it.
