During the process of EBBA2 data collection we engaged in a pilot data collection in order to be prepared for the final data collection. Below, you can find links to pilot maps of 15 species that were selected and which are showing the occurrence, breeding evidence, abundance and changes in comparison to the first European Breeding Bird Atlas. However, do bear in mind that these pilot maps were produced with incomplete data set (from 2013 till 2016), and that the final data collection has took place at the end of 2017. We are currently in the process of making the analysis of the final data we received and are preparing the publication, so the pilot maps shown here will most definitely be different than the final maps produced in 2020.
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.
