In particular, we produced four different 50×50 km maps showing: occurrence, breeding evidence, abundance and changes in species distribution in comparison to EBBA1.
These pilot maps are available for the following species: Great Cormorant (Phalacrocorax carbo), European Shag (Phalacrocorax aristotelis), Northern Harrier (Circus cyaneus), Baillon’s Crake (Porzana pusilla), Eurasian Oystercatcher (Haematopus ostralegus), Common Sandpiper (Actitis hypoleucos), Common Black-headed Gull (Larus ridibundus), Yellow-legged Gull (Larus michahellis), Rose-ringed Parakeet (Psittacula krameri), Eurasian Eagle-owl (Bubo bubo), European Bee-eater (Merops apiaster), Sardinian Warbler (Sylvia melanocephala), Wallcreeper (Tichodroma muraria), Eurasian Blackbird (Turdus merula), Northern Wheatear (Oenanthe oenanthe).
Example of the pilot maps for Sardinian warbler, with an additional modelled pilot map of probability of occurrence is presented below.
Preliminary occurrence map for Sardinian warbler (50×50 km)
Preliminary map of breeding evidence for Sardinian warbler (50×50 km)
Preliminary map of abundance for Sardinian warbler (50×50 km)
Preliminary map of change in distribution in comparison to EBBA1 of Sardinian warbler (50×50)
In addition, we produced the first pilot EBBA2 high resolution map (10×10 km) for the Sardinian Warbler (Sylvia melanocephala) using the preliminary set of standardised data provided by national coordinators in the second data provision and ensemble prediction of seven species distribution models (ANN, BRT, FDA, MARS, RF, GAM and GLM). This first modelled pilot map shows a few inconsistencies with our current knowledge of the species distribution and will be improved with the final data.

All these cartographic data are available at the EBBA2MapViewer, a special tool produced to visualise these and the forthcoming maps of this exciting project. These maps were produced through pilot data provision request sent to all national coordinators within the EBBA2 scope, and are an updated version for the five species that requested in the first pilot data provision. Detailed information on the characteristics of the first pilot data provision is available in Bird Census News 2014: 27.
We thank all the community of European ornithologists and birdwatchers that made this step in EBBA2 possible. We would like to mention here the national contacts who reported data for our third data provision on behalf of many persons and organisations: Taulant Bino & Mirjan Topi (Albania), Clara Pladevall (Andorra), Karen Aghababyan (Armenia), Norbert Teufelbauer (Austria), Elchin Sultanov (Azerbaijan), Anastasiya Kuzmenkova & Alexandre Vintchevski (Belarus), Jean-Yves Paquet & Anny Anselin (Belgium), Dražen Kotrošan & Jovica Sjeničić (Bosnia and Herzegovina), Stoycho Stoychev & Svetoslav Spasov (Bulgaria), Vlatka Dumbovic & Tibor Mikuska (Croatia), Christina Ieronymidou (Cyprus), Karel Štastný & Vladimír Bejček & Zdeněk Vermouzek (Czech Republic), Charlotte Moshoj & Thomas Vikstrøm (Denmark), Uku Paal & Jaanus Elts (Estonia), Aleksi Lehikoinen (Finland), Jérémy Dupuy, Bernard Deceuninck, Jean-Philippe Siblet & Frederic Jiguet (France), Guillermo Mayor & Alexander Abuladze (Georgia), Bettina Gerlach, Christoph Sudfeldt & Christoph Grüneberg (Germany), Danae Portolou (Greece), Karoly Nagy, Zsolt Nagy & Tibor Szep (Hungary), Gudmundur Gudmundsson & Kristinn Skarphedinsson (Iceland), Brian Caffrey, Olivia Crowe & Justin Walker (Ireland), Roberto Lardelli & Lorenzo Fornasari (Italy), Askar Isabekov & Olga Voltzit (Kazakhstan), Qenan Maxhuni (Kosovo), Viesturs Kerus & Andris Dekants (Latvia), Georg Willi & Peter Knaus (Liechtenstein), Liutauras Raudonikis (Lithuania), Patric Lorgé & Mikis Bastian (Luxembourg), Metodija Velevski & Danka Uzunova (Macedonia), Joanna Mandila & Nicholas Barbara (Malta), Mihailo Jovičević & Darko Saveljić (Montenegro), Kjetil Mork, Ingar Jostein Øien & Paul Shimmings (Norway), Tomasz Chodkiewicz & Tomasz Wilk (Poland), Domingos Leitao, João Rabaça & Carlos Godinho (Portugal), Vitalie Ajder, Silvia Ursul & Emanuel Baltag (Republic of Moldova), Judit Veres-Szászka & Zoltan Szabo (Romania), Olga Voltzit & Mikhail Kalyakin (Russia), Dimitrije Radisic, Draženko Rajković, Saša Rajkov, Slobodan Puzović & Milan Ružić (Serbia), Jozef Ridzoň (Slovakia), Tomaž Mihelič (Slovenia), Juan Carlos del Moral & Blas Molina (Spain), Fredrik Haas, Ake Lindstrom & Martin Green (Sweden), Hans Schmid & Peter Knaus (Switzerland), Chris van Turnhout & Dirk Zoetebier (The Netherlands), Kerem Boyla & Eylül Dizdaroğlu (Turkey), Justin Walker, Dawn Balmer & Simon Gillings (UK), Igor Gorban & Tatiana Kuzmenko (Ukraine), as well as international on-line portals BirdTrack, eBird, Observation.org & Ornitho, regional sources & foreign birdwatchers, with special mention to Stephan Ernst (Albania), Kai Gauger (Azerbaijan) & Johannes Kamp (Kazakhstan).
