Undersøgelse af Vandrefalken i Sydgrønland: Feltrapport 2009

This report presents results from the 27th 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 2009 they produced 2.9 young/successful site and 1.9 young/occupied territory. Fragments from hatched eggs collected in 8 nests, and moulted feathers from the adults collected at 7 nests. Among 8 nests, the first egg hatched between 27 June and 20 July (mean 7 July) - a little later than the average (4 July) for 1981-2009).
