Raptors

Birds of prey that hunt and feed on small animals.

Raptors

Raptors have keen vision that allows them to detect distant prey, which consists of small animals that are hunted with powerful talons and beaks. Most raptors supplement their diet with carrion, while vultures and condors eat carrion as their primary food source. Many species are considered apex predators. Raptors have wind-specific flight behaviors and typically hunt from perches by soaring during high winds. Soaring on thermals brings raptors to the same elevation as wind turbine blades, which can pose a high risk for collision. Raptor populations are at the greatest risk from human activities because they tend to be long-lived, mature late, and lay few eggs. Mitigation can include locating wind farms away from prime habitat, turning off turbines during peak raptor presence, dismantling specific turbines that are shown to cause raptor deaths, and upgrading old smaller turbines with new taller turbines. Power lines may also pose risk of electrocution because larger raptors may more easily connect conductive components and may be inclined to perch atop power poles.
