What everybody else said. Report him! I don’t know how it was last year as I am new to Utah but it seems that this kind of thing has been happening a lot this year. Within the last two days my dog has retrieved 4 alive winged birds that I have not shot. 1 one day and 3 in another at various WMA's. I understand not everybody has a dog but come on people at least put in an effort. These birds were not even in hard spots to get two. 2 were in the middle of a dike, one was on a small canal, and one in the middle of a frozen marsh which you could easily walk out on to. Either people are not following their shot and not watching the bird go down or they are seeing it fly and land 200 yards away and are just too lazy to walk their butts over and pick the dang thing up. As I recall, the reg says you have to make an effort to retrieve all downed birds. This clearly is not happening .
