Going for birdwatching abroad? Then you can potentially contribute with your data to the European Breeding Bird Atlas! Here we present guidelines how to do it:
WhyThe European Bird Census Council, together with its partners across Europe, plans to produce a new atlas for breeding birds in Europe, to update the ground-breaking first atlas (Hagemeijer & Blair 1997), whose data are now 30 years old. The aim of the European Breeding Bird Atlas 2 (EBBA2) is to cover the whole of Europe, but getting data on bird distribution and abundance is difficult in some countries and regions. Therefore, any reliable information is extremely valuable, including information from holidays, birdwatching trips or other opportunities to watch and record birds during their breeding seasons 2014-2017.
WhereMany countries in eastern and south-eastern parts of Europe have the biggest difficulties to find enough local fieldworkers and foreign birdwatchers are particularly welcome there. Please see the list of priority countries below and click on the country name to open a google map).

WhatCoordinators of national atlases/EBBA2 national contacts are the best placed to provide details of data required and their format. We encourage anybody interested to contribute to contact national coordinators. Nevertheless, simple data requirements, based on EBBA2 methodology apply to any country. In principle, data collected for the atlas, can come from
Both approaches will contribute to the production of European distribution maps (in a grid 50x50 km), the latter will be also used for modelling the distribution in Europe at a scale of 10x10 km. For details see the EBBA2 methodology.
1. Non-standardised survey (opportunistic data).
Minimum requirements on the data are very simple:
Geographic location and type of information:
There are different possibilities to contribute:
2. Standardised survey (timed visits)
The aim is to obtain complete lists of species with controlled effort. The data will be used for modelling species’ distribution at 10x10 km scale across Europe. Details of the standardised surveys can differ from country to country, thus, in case you are interested in this type of fieldwork, we recommend to contact national coordinators and ask for detailed instructions. European coordinators may also act as contacts and provide square grids when necessary.
However, if you cannot fully contribute to standardised surveys for a particular country (e.g. if two visits are required but you are only staying for a short time) you can still contribute to the standard survey of the European atlas. All you have to do is to report a list of species during a timed visit of 1-2 hours following a walked route (not staying in the same place). Timed visits should be done during the time of day birds are most active, i.e. usually early morning. Thus, the data requirements are:
Both approaches can be easily combined. For instance, you can start with a timed visit early in the morning, and can spend the rest of the day visiting different habitats searching for other species.

WhenBreeding season, i.e. spring from c. 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.
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.
Data deliveryThe data can be delivered in a simple format (e.g. Excel spreadsheet) containing the required information (see above for data requirements for standardised and non-standardised surveys). We prefer that data are delivered to national coordinators, who are best placed to validate them before submitting them to the European coordinators. Direct delivery to the European coordinators is also possible. In such cases, we will always check the data with the national coordinators, and we will provide them with the data from their countries.
Online recordingSome countries use an on-line recording portal, where your observations could be easily entered and thus become available to the national coordinator. Using the national portals is recommended where possible. However, if you have difficulties using the national portal (e.g. for language reasons) we recommend to use the following portals with international coverage:
If you use BirdTrack, the Ornitho app or Observation.org, data will be passed on to national coordinators and to the central EBBA2 coordination. Make sure that you tick the appropriate boxes when you subscribe to a scheme to allow data transfer.
If you want to use other portals, such as Ebird or if you are unsure what portals to use, please contact the European coordinators for advice.
