Golden Eagle was my second thought after the Rough-legged. It would be more turkey sized. The description fits with the big BUT it had a white throat and neck. Was somehow in its eating the feathers were squished to the sides revealing the underneath down feathers? The white spot on underside of wing and tail match the description of an immature golden eagle. Nancy (White's Construction) Danby, VT

FYI, pretty much all birds will eat carrion if they come across it.
I've seen gangs of robins, for example, pecking vigorously at road kill in front of my house.
Also, what looks black from a distance is likely to be dark brown seen closer up or in better light, so when thinking about what this bird might be, don't stick to black birds. Some Western Red-tails can indeed be a very dark black-brown, and they do show up in VT from time to time.
A Golden Eagle is the only NA raptor I know of that would be capable of taking down a calf, or would be inclined to try, although with birds, you can never say never. The successful ones are generally opportunistic. Fish-eating Osprey will happily take squirrels when the opportunity presents itself.
I'm stumped by the white patches on what I interpret to mean the primaries, too. I have no guesses, unless this is some kind of bilateral leucistic feathers.
