One of my Muscovy drakes was killed this morning sadly, I'll for sure miss him a lot but I have to admit I'm grateful it wasn't one of my very favorite ducks. 
Anyways, all that was left was a wing and a foot and some feathers. Where I live, it's in a fairly busy neighborhood in FL and I know what predators we have, which include hawks and raccoons. We have red shouldered hawks and most of them are as big as or smaller than my hens. (all Muscovies) We have one big red shouldered I see around but there's no way it could carry off a big drake. Lately we have caught and removed 3 raccoons, and while I'm sure there are more around, I have seen 0 evidence of one in a long time, plus they normally leave their kill. Perhaps it was possible the body got dragged off?
My guess was it could have been an eagle. I say this because a few weeks ago, I thought I saw a hawk in a nearby tree and went to chase it off. When I got closer as it flew away, I realized it was way too big and the wrong color. From googling and from my knowledge, the biggest possibility of what it could be would be a juvenile bald eagle. It's pretty rare to see one near our house but I have heard and seen one flying nearby in the sky. For this particular juvenile, I haven't seen it since.
But: is it possible it could have been an eagle?
I just don't know what it was, and I'm worried it'll be back for more of my birds. Thanks so much for any replies.
