Based on carcass present, not a wild canid (Red Fox, Coyote, Gray Fox) or Bobcat.
Based on nasty appearance of remaining feathers, a mammal inclined to eat near kill sight. Hawk or owl would make for a less bloodied / wet remaining feathers. Somebody rolled the carcass around a lot while eating.
Too much consumed for something like a mink or smaller. Since a Pekin Duck, that much carcass consumed likely involved more than one consumer.
My first guest will be more than one raccoon dining out together. Opossums possible, but not likely eating together.
