Based on the results of studies in 2010 and 2022, we modeled Saker Falcon distribution in Google Earth Engine using the image classification method – Random Forest (probability + regression). The area of Saker Falcon breeding biotopes in Karatau and adjacent territories is calculated at 4222.64 km2, area of habitats – 9084.3 km2. Saker Falcon population in the study area for 2010 is estimated at 128–281 pairs, 200 pairs on average; in 2022 – 28–66, 46 pairs on average, with a decrease by 77%. The “catalyst” for the collapse of the Saker Falcon population in Karatau is a prolonged depression in the number of rodents. Pairs that survive while nesting almost exclusively feed on birds. The preserved resource is important for population recovery, and the further fate of the species will depend both on restoration of rodent populations and on the pressure of other negative factors, such as poaching and mortality on overhead power lines.","PeriodicalId":330422,"journal":{"name":"Raptors Conservation","volume":"403 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116390036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

About 40% of the region was surveyed during this study. In 2018-2020 an EIE counting was done on our study plots covering suitable nesting habitats of the species and 78 individuals of EIE were recorded. Comparing with 2005–2012 count when 81 EIEs were recorded and the population size was estimated as 50 breeding pairs it is possible to conclude that the population nowadays is stable. However, in some local breeding groups, the number is tending to decline. For instance, in the pine forests in the valley of the Siversky Donets river, the decline is caused by habitat destruction and human disturbance during the breeding period due to woodcutting. To prevent the future decreasing, since 2016 a new legislation prohibits logging activity in woodlands of Ukraine from the 1st of April till 15th of June. On the contrary, in the agricultural area in the south and southeast of the Kharkiv region, population growth was observed. In 2018–2020 we found 29 inhabited nests of Eastern Imperial Eagles located in agricultural open lands (16 nests), in vast oak forest (1 nest), and in pine forests of the Siversky Donets river valley (12 nests). In 2019, a significant difference was found in the breeding success of pairs inhabited agricultural lands (100% successful cases) that in pine forests (40%).","PeriodicalId":330422,"journal":{"name":"Raptors Conservation","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114285762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Every autumn this flyway is used by a significant proportion of the global population of such raptor species as Honey Buzzard (Pernis apivorus), Montagu’s Harrier (Circus pygargus), Pallid Harrier (C. macrourus) and Marsh Harrier (C. aeruginosus). At least 1% of the global population of 10 raptor species migrates through the Batumi flyway. Batumi Raptor Count is of vital importance for the development of ecotourism in the region, creating an economic, political, and social foundation for raptor conservation and contributing to a reduction of widespread illegal hunting. The project also works to introduce ecology and conservation into local schools and higher education programs. This manuscript’s aim is to summarise the 13 years of the BRC. It contains a detailed description of a typical migration season in one of the most important bottlenecks for raptor migration globally. The current manuscript is loosely based on the publication in British Birds summarising the history of the BRC (Hoekstra et al., 2020). The main difference, apart from publishing it in Russian, is in taking into account the data obtained in 2021 and emphasising the importance of the autumn migration monitoring in Batumi for the conservation and research of the Russian raptor populations.","PeriodicalId":330422,"journal":{"name":"Raptors Conservation","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124963045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The northernmost limit of its breeding range is located in Kazakhstan and is fragmented into three large enclaves. The Karatau range is one such enclave. It was previously assumed that a small number of Egyptian Vultures nested here; however, research showed the fallacy of such ideas in 2010. In 2022, Karatau was surveyed in more detail to detect Egyptian Vultures. Based on the results of studies in 2010 and 2022, we modeled Egyptian Vulture distribution in Google Earth Engine using the image classification method — Random Forest (probability + regression) and calculated its possible abundance in Karatau utilizing several methods, including Distance Sampling. The area of Egyptian Vulture breeding biotopes is calculated to be 10,378.85 km2, habitat area – 34,576.8 km2. The Egyptian Vulture population in Karatau for 2022 is estimated at 171–298 breeding pairs (average of 278 breeding pairs), and 43–74 successful pairs (average of 69 successful pairs) (91 breeding territories are known). Based on obtained data and publications analysis, we assume that the Karatau Egyptian Vulture population is stable despite deterioration in habitat quality and reduction in breeding success of the species in recent years.","PeriodicalId":330422,"journal":{"name":"Raptors Conservation","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121880715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
