I have no experience with badgers, just ground hogs that dig holes in the hayfield that you don't see, and then you drop an axle in it and break something... but I have enough experience with black buzzards that I will shoot every single one that I can if it is anywhere near my cattle. They have gone into sheds and eaten baby calves alive... from the butt end, tearing them apart when they are recovering from scours... they have surrounded a heifer calving and without intervention, they would have eaten that calf before it even had a chance to stand up. They have attacked lambs; the ewe has one and then after maybe a few minutes, gets up and moves a few feet away and goes on to have the twin and they are there pecking out the eyes of the first one born... the black ones do not just eat carrion, they will attack and eat and kill perfectly healthy animals, in the form of brand newborns, because they operate in "packs".....
I know of NO ONE that has any use for the black buzzards. And they attack and drive out the true naked neck (turkey) buzzard here that eats dead stuff on the roads and does not bother the livestock.
