“…Earlier studies have shown that in Peregrines, natal dispersal distances are greater than breeding dispersal distances (Mearns & Newton 1984). The mean natal dispersal of the species is estimated to be around 80-220 km for females and 60-110 km for males, with distances of over 3000 km recorded (Mearns & Newton 1984, Zuberogoitia et al 2009, Dennhardt & Wakamiya 2013, Faccio et al 2013. Information on breeding dispersal distances is scarce, but distances of 12-90 km for females have been reported from Russia (three females dispersed of nine birds followed; Sokolov et al 2014) and 29 km in Scotland (Newton 1979).…”

Dispersal is a process that increases genetic diversity and genetic connectivity of populations. We studied the turnover rate of breeding adults and genetic population structure to estimate dispersal in Peregrine Falcons in Finland. We used relatedness estimates among Finnish Peregrine Falcons over a 5‐year period, genotyping over 500 nestlings with 10 microsatellite loci to reveal the rate of turnover. Our results reveal a high turnover rate (21.7%) that does not seem to be correlated with the breeding success of the previous year. The extent of population genetic structure and diversity, and possible signs of the population crash during the 1970s, was assessed with a reduced dataset, excluding relatives. We found genetic diversity to be similar to previously studied falcon populations (expected heterozygosity of 0.581) and no population genetic structuring among our sampled populations. We did not find a genetic imprint of the past population bottleneck that the Finnish Peregrine population experienced. We conclude that high dispersal rates are likely to have contributed to maintaining genetic diversity across the landscape, by mixing individuals within the species’ distribution in Finland and thus preventing genetic structuring and negative effects associated with the population decline in the 1970s.

“…However, the sharing of some haplotypes on a global basis may be more reflective of contemporary dispersal, whether natural or human-mediated through recovery efforts, which would erase the relationship between population-level haplotype genetic distance and geography (Neigel andAvise 1993, Oomen et al 2011). The Peregrine Falcon does exhibit maternal-biased dispersal (Mearns and Newton 1984, Tordoff and Redig 1997, Dennhardt and Wakamiya 2013, Faccio et al 2013) and a remarkable ability to reach all corners of the globe, whether during migration (e.g., from Greenland to southern Chile; del Hoyo et al 1994) or as pioneering dispersers (e.g., a nestling banded at Lake Powell in the southwestern United States was later recovered in Japan; B. Anderson, Falcon Research Group, Bow, Washington, U.S.A. pers. comm.).…”

This paper reviews the literature on survival estimates for different species of raptors and owls, examines the methods used to obtain the estimates, and draws out some general patterns arising. Estimating survival usually involves the marking of birds so that they can be recognized as individuals on subsequent encounters. Annual survival can then be estimated from: (1) birds ringed at known age (usually as nestlings) and subsequently reported by members of the public (usually as found dead), the ratio of recoveries at different ages being used to calculate annual survival; (2) marked breeding adults, trapped or re-sighted in subsequent years in particular study areas, with the proportion retrapped (or re-sighted) in each year being taken as the minimum annual survival; (3) live encounter (trapped or re-sighted) of birds marked either as nestlings or breeding adults analysed using the capture-mark-recapture (or re-sighting) methods to estimate annual survival; (4) a combination of reports of known-age dead birds and re-trapping/re-sighting of live birds; (5) use of radio-or satellite-tracking to follow the fates of individuals; and (6) the integration of these methods with other information, such as change in numbers between years, to derive estimates of survival and other demographic parameters. Studies confined to particular areas usually give estimates of 'apparent annual survival', because they take no account of birds that leave the area. However, radio-or satellitetracking makes it possible to estimate true survival, including survival of prebreeders that have low natal-site fidelity (this usually requires satellite telemetry). As in other birds, the preferred method for estimating survival has changed over time, as new and more robust methods of estimation have been developed. Methods 1 and 2 were the first to be developed, but without statistical underpinning, while methods 3-6 were developed later on the basis of formal statistical models. This difference has to be borne in mind in comparing older with newer estimates for particular species. Published survival estimates were found for three species of Cathartidae, one of Pandionidae, 29 of Accipitridae, 12 of Falconidae, one of Tytonidae and nine of Strigidae, almost all from temperate Northern Hemisphere species. In most of these species more than one estimate was available, and in some separate estimates for different age or sex groups. The main patterns to emerge included: (1) a significant tendency for annual adult survival to increase with body weight, smaller species having annual survival rates mainly of 60-70%, mediumsized species having rates mainly in the range 70-90% and the largest having rates of > 90%, in the absence of obvious human-caused losses; (2) a lower survival in the first or prebreeding years of life than in subsequent years; (3) a lack of obvious or consistent differences in survival between the sexes, where these could be distinguished; and (4) in
