Productivity of Reintroduced Peregrine Falcons in Western North Carolina
Observers monitored a reintroduced peregrine falcon population in western North Carolina from 1987 to 1992. Five of 9 occupied territories produced 19 fledgling peregrines during the study. Productivity for the period was 0.59 young fledged per territory-holding pair per year when using the full data set and 0.79 young fledged per territory-holding pair per year when we dropped marginal territories and 1 adult-subadult pair from the data set. Both estimates of productivity were below that thought necessary for a self-sustaining population. Biologists should improve their monitoring of the...
