Many studies have examined the effects of weather on avian breeding success (e.g. Ojanen 1979; Wingfield 1984, 1988; Peach et al. 1991; Clarke and Johnson 1992; Hendricks and Norment 1992; Aebischer 1993; Sasvari and Hegyi 1993), but few studies have dealt specifically with raptors (e.g. Ridpath and Brooker 1985; Mearns and Newton 1988; Olsen and Olsen 1988, 1989a,b; 1992; Pietiainen 1989; Norriss 1995; Steenhof et. al. 1997). Similarly, breeding success of Peregrine Falcons (Falco peregrinus) has been studied throughoutheir range (see Hickey 1969, Cade et al. 1988), but only two studies have evaluated the effects of weather on breeding success (Mearns and Newton 1988, Olsen and Olsen 1989b). We gathered data on 310 territorial pairs of Peregrine Falcons (Falco peregrinus) over 13 breeding seasons to explore the relationship between breeding success and weather. Specifically, we examined annual variability in breeding success and the extent to which breeding success varies with weather. We also examined weather and breeding phenology, as this relationship affected breeding success. The two previous studies of weather and breeding success in Peregrine Falcons (see above) took place in relatively benign climates. In contrast, the climate at our study area in subarctic Canada ranks among the coldest and harshest within the species' breeding range
