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...
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...
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...
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...
Distribution of nest sites and reproductive success were
determined for prairie falcons breeding in Oregon during 1973 and
1974. The study area encompassed a major portion of the eastern
half of the state. I located and monitored 63 breeding attempts during
the study and found nest sites in a variety...
