Scott, I've shot several unwanted pests around my 1 acre pond. So far, I've seen no effect on other birds, deer, turkey and other wildlife coming back in a very short time. I've even seen cormorants flying a short ways, landing in a tree and waiting for me to leave.
A friend told me that a heron is extremely wild. He had to hunt one like deer. In other words sit still and use a scoped rifle. Yep, Thats what he told me. He also told me that its illegal to kill them.
