[Nightingale]

I don't really think I would like to have bear in my yard....lol. I have a friend that lives in the up of Michigan that deals with bears at her birdfeeder and she sends me pictures...amazing creatures but a bit scary.

I think you are absolutely right about the fox feeding so close to your house because that's where it feels the least threat from other predators.
I am wondering if you might have a family of young foxes that have lost their mother and are trying to survive on their own. If they don't have much experience in survival they might be eating what leftovers they can find from the bigger predators in the area.
I suppose the fawn could have already been dead when they found it too.

I don't know of anything you can do except trap the poor things and take them elsewhere. The conservation officers around here will do that sometimes, it depends on the animal and the situation.
Maybe get a really big dog....dogs really help keep the wildlife population down in a yard.

I wish you luck and I am hoping you get some help. It isn't very much fun to have to deal with issues like dead animal parts and scat no matter where you live.

Keep me posted on what happens....I am really intersted to see if the foxes move on at some point.
