  • Foraging ecology of prairie falcons in northern California

    Creator:
    Haak, Bruce A.
    Abstract:
    Nine Prairie Falcons (Falco mexicanus) were radio-tagged in northern California during the spring and summer of 1976 and 1977 to study foraging behavior. The mean home range size for 3 males was 227.8 km²; largest portions of the home range were used during the incubation period. Shifts in foraging areas...

  • Prey selection by peregrine falcons during the nestling stage in Alaska

    Creator:
    Hunter, Robin E.
    Abstract:
    Proper management of peregrine falcons (Falco peregrinus) includes management of its prey. Little quantitative data on prey selection by peregrine falcons have been collected. The objective of this study was to determine species and relative abundance of prey brought to eyries by peregrine falcons during the nestling stage and to...

  • Parental care of peregrine falcons in interior Alaska and the effects of low-altitude jet overflights

    Creator:
    Palmer, Angela G.
    Abstract:
    To assess the impact of low-altitude jet overflights on parental care, we examined nest attendance, time-activity budgets, and provisioning rates of 21 Peregrine Falcon (Falco peregrinus) pairs breeding along the Tanana River, Alaska in 1995 and 1996. Several intrinsic and extrinsic factors influenced attributes of nesting behavior. Female nest attendance...

  • Effects of jet aircraft overflights and other potential disturbances on behavioral responses and productivity of nesting peregrine falcons

    Creator:
    Nordmeyer, Dana L.
    Abstract:
    In order to examine the potential impact of military jet overflights and other disturbances on productivity of peregrine falcons (Falco peregrinus), we observed behavioral reactions of peregrines to disturbances at nests along the Tanana River, Alaska during the 1995-1997 breeding seasons. Military jets conducted low-altitude flights over a sample of...
