Feral swine also prey directly on the nests, eggs, and young of native ground nesting birds and reptiles, including threatened or endangered species. Game birds such as wild turkeys, grouse, and quail can also be impacted. Feral swine have even been documented killing and eating deer fawns, and actively hunting small mammals, frogs, lizards, and snakes.
Feral swine wallows are prime mosquito habitat which contributes to the prevalence of various mosquito-borne diseases. Wallows can also be a place of transmission for bacteria and parasites from feral swine to native wildlife that come to drink.
