Eagles and turtles, and any number of carnivorous predators that can catch one will eat ducks. Many of the predators, including raccoons and possums will raid duck nests and eat the eggs. My uncle saw a large mouth bass swallow a duckling during one of his fishing trips. Don't forget that people find ducks to be good eats, too.
===============================
Most any carnivore or omnivore that is able to catch or find a duck could eat it. Ducks might be captured and eaten as adults, or they might be eaten as young while in or out of the nest. Duck eggs, like most all bird eggs, are also vulnerable to predators.
Ducks live in most parts of the world, they typically next at ground level, and their ducklings both walk and swim before they can fly, which means they have a very wide variety of natural predators.
============================================
Among the more common predators that prey on ducks are humans, fox, coyote, mink & weasels, wild cats, bobcats, pumas, hawks, falcons, owls, eagles, ocean birds such as heron, large fish like pike or sharks, and reptiles like snakes or alligators and crocodiles.
Bears, foxes, dogs, cats, hawks, falcons, eagles, big snakes, Fichte's, weasel's, pretty much any predatory animal.
Snapping turtles, too. Ducks are really never really safe wherever they are.
Ducks are on the diet of many, many creatures. Birds of Prey will eat a duck as will alligators/crocodiles, constricting and poisonous snakes, and man. Any carnivorous predator larger than the duck will eat it, too. This includes, but is not limited to foxes, coyotes, lynx, bobcat, mountain lion and other members of the feline family, wolves, bear, vultures, carrion eaters. Carnivores that will eat a duck are as varied as the regions/countries/continents where they are found.
