EBBA2 in a nutshell
596 breeding bird species
10 years of work
48 national partners
5 years of fieldwork
5,110 50-km squares with information
556 full species accounts
69 species treated in the appendix

446 change maps
568 illustrations of species by 46 artists
348 authors of species texts
The EBBA2 project was carried out by the EBCC network of partner organisations from 48 countries. In total, around 120,000 fieldworkers contributed data to the atlas, the great majority of them on a voluntary basis. As such this project constitutes one of the biggest citizen science projects on biodiversity ever. Data collection and analysis followed a rigorous scientific protocol, led by a team of researchers from ornithological institutes with many years of experience in atlas work.
The huge fieldwork effort resulted in unprecedented geographical coverage for a biodiversity atlas in Europe, including all areas up to the Ural Mountains and the Caspian Sea that were not well covered for EBBA1. These data were mainly collected for the period lasting from 2013 to 2017.
The book presents information on all species reported to breed in the study period and some with more uncertain breeding status. A total of 556 species are treated with a full species account including maps, text and an illustration; information on 69 very rare or irregularly breeding species is presented in an Appendix. Full species accounts include distribution maps at a resolution of 50×50 km (usually showing abundance data), modelled distribution maps with a resolution of 10×10 km (for 222 breeding birds) and change maps documenting changes in distribution since the first atlas.
This book represents the most up-to-date source of information on bird distribution and change in Europe, and a great contribution to the global aim of understanding biodiversity to ensure its conservation.
