Domestic sheep predation
Other than parasites and disease, predation is a threat to sheep health and thereby the profitability of sheep raising. Sheep have very little ability to defend themselves, even when compared with other prey species kept as livestock. Even if sheep are not directly bitten or survive an attack, they may die from panic or from injuries sustained.〔 However, the impact of predation varies dramatically with region. In Africa, Australia, the Americas, and parts of Europe and Asia predators can be a serious problem. In contrast, some nations are virtually devoid of sheep predators. Many islands that are known for extensive sheep husbandry are suitable largely because of their predator-free status.〔 Worldwide, canids—including the domestic dog—are responsible for the majority of sheep deaths.〔 〕 Other animals that prey on sheep include: felines, bears, birds of prey, badgers, hyenas, ravens, moths, prairie dogs, pandas, feral hogs and raccoons. Sheep deaths have even been attributed to cryptids such as the Chupacabra, big cats in Britain, smurfs, and the Drekavac.
==Relation to sheep behavior==
Sheep flight behavior is cited in one major study in California as the major stimulus responsible for eliciting predatory behavior in coyotes. Even coyotes that had not previously been exposed to sheep demonstrated predatory behavior when exposed to them for the first time. Of particular interest was that coyotes with no previous prey-killing experience readily attacked and killed sheep when given the chance. The coyotes were likely to attack sheep that exhibited flight behavior even when these coyotes were not hungry. The same study also determined that dominant coyotes were more likely to attack sheep.
