![]() Birds of prey can scare birds and cause them to jump or fly up, allowing their heads to protrude through the meshing. This occurs when birds are kept in a pen enclosed by loose meshing. Foxes, skunks, opossums, jays, and crows often leave shells of consumed eggs behind. Missing or damaged eggs may be caused by skunks, snakes, rats, opossums, raccoons, coyotes, foxes, blue jays, and crows. Unprotected nests are easy targets for predators. Most predators of poultry will kill and remove chicks, often without any signs of disturbance, especially if the attack occurs at night. Missing eggs or chicks-opossums, skunks, rats, cats, snakes, coyotes, foxes, and birds of prey Bobcats typically hunt during the hours of dawn and dusk, but can attack any time of day. Feathers and a few scattered pieces may be left behind after dog, coyote, and fox attacks. Coyotes are active night and day, though when living in urban areas amongst humans, they are more active at night. Often, domestic dogs will not eat the birds, and the carcass may be found in close proximity to the site of attack. ![]() Patterns of Predation Missing adult birds-coyotes, bobcats, dogs, birds of prey, and foxesįor birds of prey, hawks will take birds during the day whereas, owls will take birds during the night. Domestic animals, such as dogs and cats, can also be predators of poultry. Predators include coyotes, foxes, bobcats, weasels and their relatives, birds of prey, racoons, opossums, skunks, rodents, and snakes. Younger, smaller birds are also more susceptible. Chicken flocks are often more prone than turkey flocks, due to the size of birds. PredatorsĪ number of different predator species can cause damage and economic losses on poultry flocks. Flocks are at the highest risk, especially during the night, if they are not provided with predator-proof housing. Organic operations are also prone to predation if birds are raised free-range, where they are allowed to graze. In addition, they may not be housed at all, allowing the birds to free-range and take cover under existing structures. Commercial flocks are at risk from small predators and birds of prey when the building structures are not maintained.īackyard flocks, maintained by small farmers, hobbyists, and youth, are usually housed in a variety of facility types that may or may not offer secure predator protection. These buildings are usually constructed with concrete foundations and a complete roof, and open areas are enclosed by fine net-meshing (i.e., broilers and turkeys) or enclosed entirely by metal siding (i.e., layers). The reason for this difference is in the way flocks are housed and managed.Ĭommercial poultry producers maintain flocks within buildings for their entire production cycle. ![]() However, predation is a big concern for backyard flocks and organic poultry producers. Wolves typically hunt in packs, but have relatively low kill rates with reported results between 5-28%.Predation is not common in commercial poultry production. Lions kill about 1 in 4 prey they pursue. These cats look like they want to kill something! And they score highly on the predator success scale at a 35% success rate. how domestic cats are ruthless killers and responsible for the deaths of billions of birds. Here’s a site that discusses what those differences are.ĭomestic Cats: I’ve previously posted an IFOD on. They look almost identical to Cheetahs but there are differences. Leopards kill about 40% of prey they pursue. Peregrine Falcons have a nearly 50% success rate. And Cute! African Black-Footed CatĬheetahs kill at about a 60% rate also (one study reported 58%) And they are tiny! Only about 8-10 inches tall. African Wild DogĪfrican Black-Footed Cats have a 60% success rate. They’re super-fast clocking over 40mph sprints. These dogs differ from domestic dogs in that they only have four toes instead of five. Fortunately, they don’t eat humans! Deadly but beautiful! Here’s the success rates of other animals:Īfrican Wild Dogs have a 80-85% success rate. Researchers think that the Dragonfly is such a successful hunter due to special neurons in its brain and the design of its eyes that allow it to track a moving target and calculate an optimal intersect trajectory. The predator with the highest success rate is the Dragonfly with a shockingly high 95% success rate. While we might think that once a predator sees and pursues prey, that the prey is toast, that’s not the case as predator success rates across the animal kingdom are pretty low, often in the 1-5% range. Predator success rate is the percentage of time a predator catches and kills prey that it stalks. Recently I read in Maria Konnikova’s excellent book The Biggest Bluff about the concept of predator success rate and which predator is the most deadly.
