Welcome to every day of my life....
DO NOT get caught harassing them!
DO NOT pick up a feather they drop
Dogs help. There's a commercial laser system that "shoots" birds with laser light, not sure if USFWS would consider that harassment, and I suppose it's pricey.
We keep the dogs around and as much of a human presence as we can afford, and hope the neighbor starts calving soon. They like afterbirths better than fish.
