This dataset contains data published in the first-ever Atlas of Breeding Birds in Bulgaria which was developed and published by the Bulgarian Society for the Protection of Birds, the BirdLife partner in Bulgaria. The atlas contains the most complete information about the bird fauna of the country. It was done on the standard for Europe methodology and covers all the 1,240 10×10 km UTM squares on the territory of Bulgaria for the period 1996-2005.
The Atlas is a scientific basis for the identification of Important Bird Areas in Bulgaria (respectively the Special Protection Areas under the EU Birds Directive), for developing the new edition of the Bulgarian Red Data Book (published in 2011), for future monitoring the status of the national bird populations, as well as for successful conservation. The main sponsors of publishing this book are BirdLife/Vogelbescherming Nederland and Dutch Nationale Postcode Loterij. The main sponsors of mapping and the overall work on the Atlas are The Royal Society for the Protection of Birds - the BirdLife Partner in UK, and BirdLife International - Global partnership of conservation organisations.

The printed book (680 pages) presents information (in Bulgarian and English) on 297 bird species accounts, as well as a chapter with information on the history of bird mapping in Bulgaria, goals and methodology of the mapping, analysis and summarized data about the breeding bird fauna in the country, etc. Every species account is illustrated with a black and white drawing and presents data on population size, trends in the distribution and numbers, distribution map, a map showing the numbers of the pairs in every UTM square, historical changes in the population since 1859, preferable breeding habitats and the breeding altitude range of the species.
Unlike the atlas, for the time being, the current dataset contains only presence data (i.e. no data on species density).
Sampling Description
Study Extent
The entire territory of Bulgaria (110,990 sq. km) falls into 1,240 standard UTMs quares with a side of 10 km. The Atlas covers virtually the whole territory divided into 1,225 full or partial 10-km UTM squares. Birds were not mapped in small parts of 15 squares, situated on the very border of the country – FM35, FM53, FN12, FN13, FN49, FP04, FP12, GL38, LF37, LF66, MG31, MG94, NG43, NG74, and NJ95. The overall area not covered by the mapping amounts to about 56 sq. km (0.05% of the entire territory of the country).Sampling
The entire territory of Bulgaria was covered (110,990 sq. km, divided into 1,240 standard 10×10-km UTM squares). In total, 475 observers took part in the fieldwork. Each square has been visited and its species composition was described according to the standard methodology of EOAC. The exact or approximate numbers of the breeding pairs of each species were also estimated. The data cover mainly the period 1996-2005, although a small part was collected also in the period 1990-1995. The information gathered (over one million records) was summarised in a computerised database, being part of the National Bird Database with BSPB. Data was then analysed to calculate the size of the national population of each species, species richness per square, density of conservation significant species on the country's territory and to prepare maps.Method steps
