Peregrine Falcon
Falco peregrinus Tunstall, 1771
Birds

Threats [-]
Threats include habitat disturbance and loss, human activities, poachers robbing nests, shooting by hunters, and contamination effects (Loucks 2005). In some areas, predators such as raccoons and Great Horned Owls may decrease nest success. Human disturbances include building and bridge maintenance and recreational activities such as rock climbing, hiking, and camping near nest sites during the breeding season (NatureServe 2003). In urban areas, the mortality rate may be high due to collisions with skyscrapers and other tall office buildings.

Conservation Strategies and Management Practices [-]
Building and bridge maintenance should be reduced or restricted in nesting areas during the breeding season. Place nest boxes on buildings and bridges where Peregrine Falcons are breeding. Recreational activities such as rock climbing at popular areas during the breeding season should be limited. Develop signs and displays to inform the public of the need to protect and limit disturbances to Peregrine Falcons (Loucks 2005).

Research Needs [-]
Little is known about the mortality rate of Peregrine Falcons in urban areas. Research is needed to compare mortality rates of urban nesting birds to birds nesting in a more natural setting. Combine radio-telemetry studies with field observations to determine essential Peregrine Falcon habitat (Loucks 2005).
