The Peregrine Falcon (Falco peregrinus tundrius) population in South Greenland has been monitored annually 1981-2021 (except 1993, 2004 and 2020). At visits to known breeding sites we recorded presence/absence of territorial falcons as well as their breeding outputs (number of eggs and/or young). The file named S_Greenland_Peregrine_monitoring_data-1981-2021.csv contains the raw data from 835 site checks (sometimes several per site per year). The file named S_Greenland_Summary_occupancy_and_productivity-1981-2021.csv contains a summary of the raw data, providing annual estimates of occupancy, productivity and average brood size (young/ successful nest). The respective ReadMe files specify the contents.
