BG,"Long-term Changes in Autumn Migration of Selected Soaring Bird Species at Burgas Bay, Bulgaria
The paper presents data of the autumn migration along the Western Black Sea migration route (Via Pon¬tica) collected since 1979 with special attention to the changes of migration numbers and peak days of the ten most numerous soaring bird species. It is found long-term increase in the migration numbers of Pelecanus onocrotalus, Ciconia ciconia, Ciconia nigra, Circaetus gallicus, Circus aeruginosus, Accipiter brevipes, Clanga pomarina, Aquila pennata and Falco vespertinus. All collected data confirm that the Burgas Bay is the place with the highest and increasing autumn migration numbers of the great white peli¬can and the red-footed falcon in Europe. Four new terms (flyshed, sandglass site, migration period and peak’s migration period) have been introduced and has been proposed a classification of the sandglass sites according to the flight types and migration behaviour of the soaring birds. Additionally has been outlined the need for covering of a wider segment of the migration route through a chain of observation points, including specialised radar and the usefulness of joint and synchronised ef¬forts by all teams at the basic observation points in Europe and Asia Minor on a continental scale.",2018,"https://www.researchgate.net/publication/324170753_Long-term_Changes_in_Autumn_Migration_of_Selected_Soaring_Bird_Species_at_Burgas_Bay_Bulgaria

BG,"No Evidence for Displacement of Wintering Red-breasted Geese Branta ruficollis (Pallas, 1769) (Anseriformes) at a Wind Farms Area in Northeast Bulgaria: Long-term Monitoring Results
While broadly considered “environmentally friendly”, being a clean source of renewable energy, wind farms are not without potentially adverse effects on environmental features, notably on birds. The conservation status of the Red-breasted Goose Branta ruficollis (RBG) has changed from endangered in the past to vulnerable in 2015. At present, the hinterland of the western Black Sea coast, including Bulgaria, is one of the main wintering grounds of RBG, where flocks co-exist in the same region with around 200 wind turbines. We hypothesise that the operation of wind parks has caused displacement of wintering geese. However, according to the results of our study, RBG are using the same territory in the same number but distributed in smaller flocks. Our findings do not indicate displacement of RBG from traditional feeding grounds but are associated with the changes in the property of the land in Bulgaria and fragmentation of the crop fields, including those of wheat, which is the main feeding resource of RBG in winter. Our study provides no evidence for a displacement effect of wind turbines and describes the opportunistic strategy of wintering of RGB in the area in the last 20 years.",2016,"https://www.researchgate.net/publication/318446970_No_Evidence_for_Displacement_of_Wintering_Red-breasted_Geese_Branta_ruficollis_Pallas_1769_Anseriformes_at_a_Wind_Farms_Area_in_Northeast_Bulgaria_Long-term_Monitoring_Results

The distribution and numbers of 34 species of breeding water birds are studied along the Bulgarian section of the Danube River between 2006 and 2013. Seven synchronized counts of breeding water birds are conducted in all of the wetlands in that particular stretch. The most numerous species that have been found are the Great Crested Grebe (Podiceps cristatus), 34-78 pairs; Little Bittern (Ixobruchus minutus), 40-93 pairs; Mallard (Anas platyrhynchos), 84-148 pairs; Gadwall (Anas strepera), 30-51 pairs, Garganey (Anas querquedula), 38- 81 pairs; Common Pochard (Aythya ferina), 72-141 pairs; Ferruginous Duck (Aythya nyroca), 88-157 pairs; Coot (Fulica atra), 290-552 pairs; and Whiskered Tern (Chlidonias hybrida), 339 - 1637 pairs. Observations made during the breeding period and findings of proved breeding cases of rare or irregularly breeding species such as the White Pelican (Pelecanus onocrotalus), Ruddy Shelduck (Tadorna ferruginea), Teal (Anas crecca), Tufted Duck (Aythya fuligula), Red-crested Pochard (Netta rufina), Pied Avocet (Recurvirostra avosetta) and White-winged Tern (Chlidonias leucopterus) are also presented in this study. A long-term (last 30 years) trend indicating an increase in water bird numbers can be confirmed for the Mute Swan, Great Crested Grebe, Ferruginous Duck, Gadwall, Common Pochard and Whiskered Tern; in contrast, a decrease has been observed in the numbers of Greylag Goose, Garganey and Black Tern (Chlidonias niger).",2019,"https://www.researchgate.net/publication/334899397_Recent_data_on_the_distribution_and_numbers_of_the_water_birds_in_the_wetlands_along_the_Bulgarian_section_of_the_Danube_River

Seven recent observations of flocks or solitary birds of the species in Bulgaria during the post-breeding period are presented and commented in the publication.

BG,"Recovering the Lesser Kestrel (Falco naumanni) as a breeder in Bulgaria. 
The Lesser Kestrel (Falco naumanni) is one of the rarest raptors in Bulgaria. Although once a common species, Lesser Kestrel has not been confirmed as a breeder in the country for the past few decades. Having implemented feasibility studies, Green Balkans launched the implementation of direct actions aimed at restoring the species as a breeder in Sakar SPA, a NATURA 2000 site in Bulgaria, through release of juveniles into the wild. With regard to this approach, based on a special methodology designed by DEMA called “Ambiente de Colonia” - a combination of the so called “hacking” and “foster parenting” methods, a Lesser Kestrel Release and Adaptation Module has been established. Lesser Kestrel chicks translocated from Spain are released into the wild. The juveniles are bred in captivity at DEMA’s breeding center. A breeding stock has been established at Green Balkans’ Wildlife Rehabilitation and Breeding Center (WRBC), consisting of wild birds, which have undergone rehabilitation at rescue centers in Spain and were ceded by the Government of Extremadura (Spain). This breeding stock is also providing offspring to be released. 
A total of 286 juvenile Lesser Kestrels were released through the Module as follows – 90 individuals in 2013, 114 individuals in 2014, 82 individuals in 2015. As a result of these actions, the species has been restored as a breeder in Bulgaria. In 2014, there were 8 newly formed pairs, while in 2015 the number of breeding pairs was 9. The number of chicks that fledged in the colony in Levka village, Sakar SPA, was as follows – 15 individuals in 2014 and 17 individuals in 2015.",2015,"https://www.researchgate.net/publication/286933779_RECOVERING_THE_LESSER_KESTREL_FALCO_NAUMANNI_AS_A_BREEDER_IN_BULGARIA
