Recent variation in the reproductive output of Peregrine Falcons ( Falco peregrinus anatum ) breeding along the Yukon River has encouraged the examination of the environmental factors that influence the reproductive ecology of these birds. The objectives of this study were to examine how weather, territorial quality and prey selection by breeding Peregrine Falcons relate to productivity at nest sites. I also assessed territorial occupation frequency as a measure of habitat quality. A total of 52 territories were monitored along the Yukon River, and were surveyed 11 times from 1984-2004. The occupation frequency was highly correlated with measures of productivity at a nest and I therefore considered occupation frequency...
