This results in genetic contamination of the wild Peregrine population. The population estimate derived from the survey puts the UK Peregrine population at 1,769 breeding pairs, an increase of 22% on the previous survey (carried out in 2002). It has long, broad, pointed wings and a relatively short tail. Eagle Owls are more and more frequently taking over Peregrine Falcon nest boxes on buildings.

RSPB Scotland and Scottish Natural Heritage (SNH) both contributed to the survey. The peregrine falcon is undoubtedly one of Ireland’s most impressive birds. Population status and factors affecting the productivity of peregrine falcon Falco peregrinus in County Wicklow, Ireland, 2008–2012 Although the purpose of the surveys is not to determine population abundance, they do make it possible to estimate the minimum size of the breeding population.

The temporally averaged population growth rate in urban habitats was estimated as λ = 1.28, compared to λ = 0.99 in rural habitats. The American peregrine falcon was removed from the endangered species list in 1999. Most of the increase is accounted for by population growth in lowland England, with breeding Peregrines continuing to occupy new sites.

Yearly analytical λ values in rural habitat predict declining population growth (λ < 1) throughout the 1980s and increasing population growth (λ > 1) in the 1990s due to improved reproductive performance. The territory-density and nesting-association methods led to estimates of 1,586 (95% CI = 991 to 2,179) and 2,417 (95% CI = 1,306 to 3,528) falcon territories, respectively, across the common range of Peregrine Falcons and Red-breasted Geese; the first method suggested a population of 3,652 falcon territories (95% CI = 2,282 to 5,018) across the entire range F. p. calidus.
