Ducks face a long list of predators on land, in the air, and in the water. In North America, the most common duck predators include red foxes, raccoons, coyotes, mink, hawks, owls, large gulls, skunks, weasels, crows, snapping turtles, and large fish like northern pike. The specific threats depend on where ducks live, whether they’re wild or domestic, and how old they are.
Mammals That Hunt Ducks
Mammalian predators are responsible for a significant share of duck deaths. A U.S. Geological Survey study tracking duckling mortality found that mammals accounted for about 28% of confirmed kills. The most common culprits in North America are red foxes, raccoons, coyotes, mink, weasels, and skunks.
Red foxes and coyotes are opportunistic hunters that will take both adult ducks and ducklings, particularly nesting hens that are sitting on eggs and reluctant to flee. Raccoons are especially dangerous to nesting ducks because they’re excellent climbers, strong swimmers, and active at night when ducks have poor vision. They also raid nests for eggs. Mink and weasels are smaller but effective duck predators. Mink are semiaquatic and can pursue ducks both on land and in the water, making them a threat that few other mammals can match. They’re known to steal eggs from nests and kill ducklings and even adult birds.
Skunks are primarily egg thieves. They locate ground nests by smell and will eat entire clutches overnight. While they rarely kill adult ducks, the damage they do to nesting success is substantial.
Raptors and Other Birds
Birds of prey are the second largest category of duck predators, responsible for about 22% of duckling deaths in the USGS study. Hawks, owls, eagles, falcons, and even large gulls and crows all prey on ducks at various life stages.
Red-tailed hawks are ambush hunters that typically perch and wait for prey to come within striking distance. Great horned owls are a serious nighttime threat, capable of killing adult ducks. Bald eagles will take ducks from the water’s surface. Falcons use speed as their primary weapon. Peregrine falcons can reach speeds of 240 mph in a dive (called a stoop), while gyrfalcons, which are larger and frequently used by falconers to hunt waterfowl, can exceed 100 mph. Gyrfalcons are “seeker predators” that stay on the wing scanning for prey, and they can fly both over and under a duck to grab it with their talons.
Crows and large gulls don’t typically take adult ducks, but they’re efficient nest raiders and duckling hunters. They patrol wetlands and shorelines looking for unattended nests or small, vulnerable young.
Underwater Threats
Ducklings face dangers from below the surface that many people don’t expect. Northern pike, largemouth bass, and other large predatory fish eat ducklings. Pike in particular are indiscriminate feeders that will strike at mice, snakes, songbirds, and ducklings alike. A duckling paddling on the surface looks much like any other small prey item to a large pike lurking underneath.
Snapping turtles are another underwater predator. They grab ducklings (and occasionally adult ducks) from below, pulling them under. Snakes also take a toll, accounting for roughly 4% of duckling mortalities in tracked populations. Large water snakes and rat snakes can eat eggs and small ducklings.
How Many Ducklings Actually Survive
The predation numbers paint a stark picture of how dangerous early life is for ducks. Predation accounts for 91% of all duckling deaths. Mallard duckling survival to fledging (the point where they can fly) was less than 3% during dry years and under 17% during wetter years in one USGS study. Gadwall ducklings fared slightly better, with 9 to 11% surviving to fledging regardless of conditions.
Wetter years help because more flooded habitat gives ducklings better escape routes and more places to hide. Nests closer to summer-flooded wetlands produce ducklings with higher survival rates, largely because the young birds spend less time traveling overland where they’re most exposed to predators.
Urban Ducks Face Different Predators
Ducks living in parks, ponds, and suburban neighborhoods encounter a modified set of threats. Raccoons and coyotes still rank high, but domestic dogs and cats become major predators in these settings. Free-roaming cats are especially dangerous to ducklings, and off-leash dogs can kill or injure adult ducks.
Urban ducks are often at a disadvantage because many park populations include abandoned domestic ducks that were bred for food production, not survival. These birds are heavier, slower, and less capable of flying to escape danger. Overcrowding in park ponds also concentrates ducks in small areas, making it easier for predators to find them.
Protecting Domestic Ducks From Predators
If you keep ducks at home, nighttime is the highest-risk period. Ducks have poor night vision and are essentially defenseless in the dark. Locking them in a secure coop from dusk through dawn is the single most effective protection. Many predators, including raccoons, skunks, opossums, and owls, are most active during twilight and overnight hours.
The coop itself needs to be built with specific threats in mind. Raccoons have dexterous fingers that can open simple latches, so you’ll want locks or carabiner-style closures. The walls and any windows should be covered with quarter-inch to half-inch wire mesh, which is too small for raccoon arms to reach through or snakes to squeeze through. Standard chicken wire keeps ducks in but won’t stop a determined predator from tearing through it.
Digging predators like foxes and coyotes will tunnel under walls, so burying wire mesh at least 12 inches into the ground around the perimeter of the coop and run is important. For aerial predators like hawks and owls, a covered run or overhead netting provides protection during the day. Planting trees, bushes, or tall grasses near areas where ducks roam gives them natural cover to duck under when a raptor appears overhead. Building the coop close to ground level also helps, since ducks are clumsy on ramps and can injure themselves trying to get inside quickly when startled.
