The second Slovenian Breeding Bird Atlas was published in May 2019

Complete knowledge of 228 Slovenian breeding birds is now gathered in one book. A detailed survey of the distribution and relative abundance of breeding birds in Slovenia is based on data provided by 632 volunteers in the period from 2002 to 2017. The book includes precise distribution and relative abundance maps of species, altitude charts, species statistics, species text accounts as well as stunning photographs of species in breeding plumage. Likewise, eleven former breeders from the period 1979–2001 are included in the book (all together making 239 species).

The atlas is in Slovenian language with summaries of the species’ breeding status and distribution provided in English for all species, together with the English names at the beginning and the summary of methodology and data processing.

The precise maps of relative breeding densities are displayed for all common species, recorded in more than 120 tetrads during the abundance surveys. The data from 1592 2km line transects were used and modelled for the entire Slovenia.

Distribution maps  clearly show differences between the two atlases, the changes in a species’ breeding distribution at the level of 10-km squares between this and the previous breeding bird atlas (Geister 1995). The real change in distribution or change as an effect of more intensive survey work is discussed.

In the altitude graphs the percentage of the species’ population per 200 m of altitude change are displayed.

In total, 44 authors contributed with text accounts where species’ breeding status in Europe and Slovenia is shortly described. The main focus is distribution in Slovenia where text highlights the typical areas of the species occurrence and some interesting features of its distribution. Then the species’ habitat and breeding densities in Slovenia are described. In the event of insufficient Slovenian data, data from abroad are used and a review of research on the species in Slovenia is made. For the endangered species (category NT or higher in the Slovenian Red list) or for species for which the survey data parallel to this atlas were available and indicated the species’ decline, conservation status is presented.

At the end of each species account, there is a summary statistics such as information of its population size, number of occupied squares, and collected data.
