Recommendations Colorado Parks and Wildlife(CPW) (CDOW 2008)has provided information(in the form of guidelines) for the protection of raptor nesting habitat as it relates to disturbance that may affect a nest site. The guidelines include spatial buffer zones and temporal recommendations,which are intended to protect nesting raptors. The CPW suggests that if the guidelines are observed,that the majority of individuals within a species will continue to occupy the nesting site where disturbance is a potential factor. CPW guidelines for select species are shown in Table 3. Table 3. Timing and buffer guidelines for occupied raptor nests Species Buffer Zone Typical Nesting Season American Kestrel Burrowing Owl 150 feet 15 March—31 October Cooper's Hawk 0.25 mile 1 April— 15 August Ferruginous Hawk 0.5 mile 1 February- 15 Jul Golden Eagle 0.50 mile 15 December— 15 Jul Great Horned Owl Long-eared Owl 0.25 mile 1 March— 15 Jul Northern Harrier 0.25 mile 1 April— 15 August Osprey 0.25 mile 1 April—31 August Peregrine Falcon 0.50 mile 15 March—31 Jul Prairie Falcon 0.50 mile 15 March— 15 Jul Red-tailed Hawk 0.33 mile 15 February— 15 Jul Sharp-shinned Hawk 0.25 mile 1 April— 15 August Swainson's Hawk 0.25 mile 1 April— 15 Jul * Great Horned Owls and Kestrels are relatively tolerant of human activity. Keep activity to a minimum during breeding season. CPW will provide guidance on future survey requirements and timing limitations for project-related disturbances, if applicable.
