This report presents an enlarged set of population trends and indices of 77 common bird species in Europe, which have been produced by Pan-European Common Bird Monitoring Scheme in 2005. The trends and indices presented in this report cover time period 1980 – 2003, although data back to 60s are available from some European countries.
The Common Bird Monitoring scheme has commenced in 2004 in Bulgaria. The project aims at establishing a national widespread breeding bird monitoring scheme based on the UK Breeding Bird Survey model and incorporating the experience from other European countries.In the pilot year (2004) 74 observers took part in the scheme and Over 130 observers in 2005. First two years of the scheme bring promising results and hope to fill in a gap in common bird monitoring geographical coverage in Europe.
The review has shown that substantial progress has been made in development of common bird monitoring schemes in Europe. There are 20 countries with data potentially suitable for generating Pan-European indices for common birds. Much effort should be, however, devoted to improvement of existing national schemes and development new schemes. Full text of the review is available in PDF format.
