| Summary: | This report presents results from the 30th field season of the project “Investigations of the Peregrine Falcon in South Greenland”. Following analyses of data from the first 22 years, the primary objectives of the study since 2005 has shifted towards monitoring of a fixed sample of nesting sites where reproduction, timing of breeding and monitoring of loads and effects of contaminants are carried out annually. Twelve sites have been selected, and in 2012 all 12 sites were checked, producing 2.8 young/successful site and 1.9 young/ occupied territory. Fragments from hatched eggs were collected in 6 nests, and moulted feathers from the adults collected at 4 nests. Among 9 nests, the first egg hatched between 1 July and 10 July (mean 4 July), one day later than the average for 1981-2012. In addition, five breeding female Peregrine Falcons were fitted with geolocators.
