There's a domestic goose that lives on one of my home lakes. If you catch a small sunfish, and drop it on the ground, that goose will attack that fish with a vengeance. I know that the gent that patrols the lake (and runs the bait shop) would prefer that all the geese and ducks quietly "disappear". Feathers?????

And no, I wouldn't do anything to harm them. The City would have a problem with that. So would the neighbors that come in and feed the darn things.

Now, the hawk that lives on one lake did make a duck dinner a couple months ago.......
