How to contribute in my country

Each country within EBBA2 scope has its own national coordinator(s). If you are interested, please, contact your national coordinator, who will provide you with thorough information on methodology and data submission. See the contacts to the national coordinators.

You could also explore whether your country already has an existing on-line portal designed at entering bird data in Atlas format (specified 50×50 squares and Atlas breeding codes). As a starting point, you can check the EuroBird Portal (on-line platform with partners from 21 European countries), and look at quick overview of their partners.

How to contribute in a foreign country

If you are planning to go for birdwatching abroad then you can potentially contribute with your data to the European Breeding Bird Atlas! We need data from breeding season, i.e. spring from second half of April to end of June. Caution: the breeding season depends on latitude and altitude, climatic conditions etc. If you are not sure, please check the timing with the coordinators.

Most help is needed in countries in eastern and south-eastern parts of Europe that have the biggest difficulties to find enough local fieldworkers. Foreign birdwatchers are particularly welcome there. Please see the list of Priority countries and click on the country name to open a google map. For detailed description on methodology and data collection within individual countries, national coordinators are the best place source of information.

You can also check our Gap tool which visualizes where mapping efforts can directly be oriented within priority countries. Just select a country from the menu. There are 4 categories marked with different colours and by clicking on each square you will see the description of each category (in the case of Bosnia and Herzegovina, it is recommended to contact the national coordinator for all squares, due to the problem with minefields).


Data can be collected through non-standardised (in 50×50 km squares) and standardised surveys (in 10×10 km squares) using Atlas codes.  For more information please check data requirements for standardised and non-standardised surveys. 

You can also download the European and national grids.

You can find the detailed methodology of EBBA2 here.

You can submit your data on-line via different web-portals or contact the national coordinator. For more information see data submission.

Any reliable information is extremely valuable, including information from holidays, birdwatching trips or other opportunities to watch and record birds during their breeding season. Data from years 2013, 2014, 2015, 2016, 2017 are desirable. In case you have data slightly older, e.g. from 2012 or 2011, such data may be also useful, especially in countries with lack of data. Please consult it with European coordinators.

Please keep us informed abut your activities by filling a simple form. It enables us to keep records about effort and coverage for the European atlas.
