Résumé :
|
This paper gives an overview of occurrence and population trends of 40 threatened or rare Danish breeding birds, summarizing the results obtained in 2005 by the working group on the monitoring of the threatened and rare breeding birds. The monitoring project was implemented by the Danish Ornithological Society (Dansk Omitologisk Forening / BirdLife Denmark (DOF)) in 1998 and aims at collecting data on these species each year during the breeding season. The project is organised as a network of coordinators, each collecting breeding records and other data on one or a few species. After the breeding season the data are sent to a central coordinator, who prepares the final report. The main content of the report is the species accounts, generally written by the species coordinators as listed in Table 1.
