The historical decline of the peregrine falcon (Falco peregrinus) in North America was attributed mainly to reproductive failure associated with persistent organochlorine pollutants, in particular DD T (dichloro-diphenyl-trichloroethane). It is generally assumed that declining trends in pesticide loads will be accompanied by a corresponding increase in reproduction. In this study, we concurrently measured occupancy, reproductive performance, and pesticide loads of breeding-aged adults on territory near Rankin Inlet, Nunavut, from 1982 to 2009. Our findings indicate that reproductive success of peregrine falcons in our study population declined despite concomitant reductions in pesticide loads, and that on average, approximately three fewer ...
