Abstract In 2008, the IUCN uplisted the Curlew to near-threatened (NT) on its Red List. The bird’s population in Slovenia is localised and small, thus making it very important to be surveyed every year. Using the point count method, we recorded 9-12 breeding pairs in 2011 and 9-10 pairs in 2012 at Ljubljansko barje. Most of them were distributed in the eastern part of the area between the village of Lipe and the river Iščica, whereas only two occupied territories were discovered in 2011 and one in 2012 in the western part of the area. In a ten-year period, the area underwent agricultural intensification, with lowland non-intensive meadows declining by 50%. As a minimal requirement, meadows within the extent of the Curlew’s current distribution at Ljubljansko barje should be non-intensively managed (late first cut, no fertilizing or sowing of grass mixtures) and all other human activities prohibited from the beginning of March till the end of June (dog walking and training, ballooning, aircraft modelling). Based on the results of 2011 survey, Ljubljansko barje was designated an IBA for breeding Eurasian Curlews under the IBA criteria A1 and C1.

Abstract The altitudinal distribution, breeding density and population size of Tengmalm’s Owl Aegolius funereus was studied in Kopaonik National Park (central Serbia) during the 2011 and 2012 breeding seasons. The size of the study area was 24 km2. The survey method applied was a line transect in combination with stop points and playback of territorial male call. During the two-year research project, 37 territories were located. In Kopaonik National Park, Tengmalm’s Owl males inhabit Norway Spruce Picea abies, mixed Norway Spruce-Silver Fir Abies alba and Norway Spruce-European Beech Fagus sylvatica forests in the altitudinal belt stretching between 1,367 and 1,689 m a.s.l. The breeding density in the studied area was 8.3 territories/10 km2 in 2011 and 7.1 territories/10 km2 in 2012. Total population estimate of Tengmalm’s Owl in Kopaonik National Park is substantially higher than previously assumed, its 42-49 breeding territories making it currently the most important breeding site in Serbia.

Abstract In Finland, population monitoring for both diurnal and nocturnal raptors has been almost entirely based on fieldwork carried out by voluntary raptor ringers. Responsible organisations include the Finnish Museum of Natural History, with economic support for administration from the Ministry of Environment, “Metsahallitus” (former National Board of Forestry) and WWF Finland. Since the early 1970s, numbers and productivity of four endangered species, the White-tailed Eagle Haliaeetus albicilla, Golden Eagle Aquila chrysaetos, Osprey Pandion haliaetus and Peregrine Falcon Falco peregrinus have been monitored by country-wide Comprehensive Surveys, with the aim of checking all known nest sites of these species every year. The Gyrfalcon F. rusticolus was included in this group in the late 1990s. Data for monitoring the populations of the other raptor species have been gathered by the Raptor Grid and Raptor Questionnaire projects. The Raptor Grid project produces annual population indices, which are calculated from the data collected from 10 × 10 km study plots (n = ca. 130/year) and quite well reflect the annual population fluctuations and longterm trends of seven common species of diurnal and six species of nocturnal raptors breeding in the southern part of Finland. For the rest of the species, which are either rare all over Finland or breed mostly in the north, outside the good coverage of the distribution of Raptor Grid study plots, conclusions on population changes are based on the total numbers of occupied territories and active nests reported annually by the Raptor Questionnaires
在芬兰，对白天和夜间猛禽的种群监测几乎完全基于自愿的猛禽铃声进行的实地调查。负责的组织包括芬兰自然历史博物馆，并得到环境部、“Metsahallitus”(前国家林业委员会)和世界自然基金会芬兰分会的经济支持。自20世纪70年代初以来，全国范围内的综合调查监测了四种濒危物种的数量和生产力，即白尾鹰、金鹰、鱼鹰和游隼，目的是每年检查所有已知的这些物种的巢穴。在20世纪90年代末，Gyrfalcon F. rusticolus被列入这一群体。监测其他猛禽种群的数据已由猛禽网格和猛禽问卷项目收集。猛禽网格项目根据10 × 10公里研究地块(n =约130/年)收集的数据计算出年度种群指数，很好地反映了芬兰南部繁殖的7种常见的昼行猛禽和6种夜间猛禽的年度种群波动和长期趋势。对于其余的物种，它们要么在芬兰很少见，要么主要在北部繁殖，在猛禽网格研究区域分布的良好覆盖范围之外，关于种群变化的结论是基于猛禽问卷每年报告的被占领领土和活跃巢穴的总数

Abstract Despite the key role of raptors (including birds of prey Falconiformes and owls Strigiformes) in ecosystems and their sensitivity to environmental change, a well coordinated, Europe-wide monitoring of raptors is lacking. EURAPMON, a Research Networking Programme of the European Science Foundation, was launched with the aim of establishing a sustainable Europewide network for monitoring of raptors. An overview of current monitoring schemes for raptor populations in 28 European countries, as reported by EURAPMON National Coordinators at the workshop in Murcia (Spain) in 2012, showed existing monitoring schemes to be limited to a restricted number of species (mostly diurnal and rare raptor species). The most widely monitored species are the Golden Eagle Aquila chrysaetos amongst diurnal raptors and the Eagle Owl Bubo bubo amongst owls. Broad coverage of a species range across Europe is reached only for restricted-range species. The key driver for monitoring, which is mostly coordinated by NGOs, is conservation, and the main end users are governmental institutions. International collaboration in the field of monitoring of raptors is mainly regional and not yet pan-European in scale. The involvement of volunteers in raptor monitoring was perceived as the main strength of many schemes, but insufficient manpower and a focus on rare species were recognised as the main weaknesses across Europe as a whole. Among priorities identified for the future development of monitoring schemes are: improvements to national coordination; support to increase the number of volunteers; and assurances of stable funding. Further analysis of EURAPMON questionnaires will identify knowledge gaps, which will steer good practice guidance on survey methodologies; the need for the latter was identified as the main benefit that National Coordinators expect to gain from international networking

Abstract There are 40 regularly occurring raptor species in Croatia (diurnal raptors and owls), but only for two species (Griffon Vulture Gyps fulvus and Eleonora’s Falcon F. eleonorae) long-term monitoring (more than 10 years) of significant parts (i.e. > 80%) of their national population has been implemented. For 23 species (58%), the coverage of monitoring is limited to several locations (often within borders of given protected area), involving small percentage of national population or/and has started recently. Therefore, they do not satisfy the main purpose of national monitoring programmes, i.e. to draw conclusions about the trend of the species’ national population and to support the decision-making process about conservation measures to be applied. Besides the Institute of Ornithology and several ornithological NGOs, which are recognized as main actors for the implementation of raptors monitoring, the State Institute for Nature Protection (SINP) is setting up a framework for the nationwide bird monitoring complying with the legal provisions of the EU Birds Directive and the Natura 2000 network. The highest priority is to improve the coordination between state institutions, scientific and non-governmental organizations involved in raptor conservation with the final aim to develop a national raptor conservation strategy that sets priority target species and standardized monitoring systems
克罗地亚有40种定期发生的猛禽(昼行性猛禽和猫头鹰)，但只对两种(Griffon Vulture Gyps fulvus和Eleonora’s Falcon F. eleonorae)进行了10年以上的长期监测，监测了其全国种群的重要部分(约80%)。对于23个物种(58%)，监测的覆盖范围仅限于几个地点(通常在给定保护区的边界内)，涉及国家人口的一小部分或最近才开始。因此，它们不符合国家监测方案的主要目的，即得出关于该物种国家种群趋势的结论，并支持关于应采取的保护措施的决策过程。除了鸟类研究所和一些鸟类非政府组织被认为是实施猛禽监测的主要行动者外，国家自然保护研究所(SINP)正在根据欧盟鸟类指令和Natura 2000网络的法律规定建立一个全国鸟类监测框架。最高优先事项是改善参与猛禽保护的国家机构、科学组织和非政府组织之间的协调，最终目的是制定一项国家猛禽保护战略，确定优先目标物种和标准化监测系统

Abstract Among 48 raptor species (birds of prey, owls, shrikes) recorded recently in Slovenia, some long-term monitoring activities are being conducted for more than half of them, mainly for conservation and research purposes. However, national coverage is achieved only in 15% of the species, whereas other monitoring programmes are more or less local. Two monitoring approaches are considered, the species specific approach and assemblage approach. Current ongoing monitoring programmes for raptors in Slovenia lack monitoring of breeding success, which is now confined to only a few owl species. Use of nestboxes should therefore be considered more broadly in the future for some species at least

Abstract Since 1990, nature conservation NGOs are the main players in the running of nation-wide research and monitoring schemes for raptors in Bulgaria. Among them, the Bulgarian Society for the Protection of Birds (BSPB) and Green Balkans are most active, covering the most threatened diurnal raptors in the country. The key species covered by comprehensive monitoring schemes are the Imperial Eagle Aquila heliaca, White-tailed Eagle Haliaeetus albicilla, Egyptian Vulture Neophron percnopterus, Griffon Vulture Gyps fulvus, Black Vulture Aegypius monachus, Saker Falcon Falco cherrug and Red-footed Falcon F. vespertinus. Information on their distribution, numbers, breeding success, productivity, diet, movements etc. is gathered on annual basis. The Buzzard Buteo buteo and Kestrel F. tinnunculus are also regularly monitored at the national level by the Common Bird Monitoring scheme. Distribution of all raptor species has been studied for the purpose of the Atlas of Breeding Birds in Bulgaria. The contemporary satellite telemetry methods revealed important aspects of movements and threats to eagles and vultures from Bulgaria within the country and abroad. Main threats for the raptors in Bulgaria are related to habitat loss, unnatural mortality and disturbance. The main gaps in raptor monitoring in Bulgaria are related to the lack of coverage of most of the diurnal species and owls. There is a strong national and international cooperation in conjunction with the work concerning Imperial Eagle, Egyptian and Griffon Vultures. However, further enhancement of cooperation on other raptor species and issues such as lobbying for implementation of raptor-friendly agricultural practices and enhancement of various economic sectors are needed
自1990年以来，自然保护非政府组织一直是保加利亚全国范围内猛禽研究和监测计划的主要参与者。其中，保加利亚鸟类保护协会(BSPB)和绿色巴尔干是最活跃的，覆盖了该国最受威胁的日间猛禽。综合监测计划覆盖的重点物种有:皇鹰、白尾鹰、埃及秃鹫、埃及秃鹫、埃及秃鹫、埃及黑秃鹫、埃及黑秃鹫、埃及黑秃鹫、埃及黑秃鹫、埃及红脚隼。每年收集它们的分布、数量、繁殖成功率、生产力、饮食、运动等信息。国家一级的普通鸟类监测计划也定期监测Buteo Buteo和Kestrel F. tinunculus。所有猛禽种类的分布已被研究，目的是在保加利亚繁殖鸟类地图集。当代卫星遥测方法揭示了保加利亚国内外鹰和秃鹫活动和威胁的重要方面。保加利亚猛禽面临的主要威胁与栖息地丧失、非自然死亡和干扰有关。保加利亚在猛禽监测方面的主要差距与缺乏对大多数白天活动的物种和猫头鹰的覆盖有关。有一个强大的国家和国际合作，与有关帝国鹰，埃及和格里芬秃鹫的工作相结合。然而，需要进一步加强在其他猛禽物种方面的合作，以及游说实施对猛禽友好的农业做法和加强各种经济部门等问题

Abstract In the last 150 years, 49 raptor species belonging to the families Pandionidae, Accipitridae, Falconidae, Tytonidae, Strigidae and Laniidae have been recorded in Bosnia and Herzegovina. However, little is known about their populations. In comparison with historical data, their status has changed significantly, while nine species became extinct or probably extinct as breeders. In this paper, data on the present status of raptor populations is presented, as well as problems and the possibilities of developing species monitoring in Bosnia and Herzegovina. So far, no raptor monitoring has been established in the form of a long-term programme. The establishment of such programme is hampered by a number of reasons (lack of observers, lack of financial resources, lack of experience and knowledge, etc.). Monitoring of raptors in Bosnia and Herzegovina is needed to improve knowledge of the local populations as well as to protect these birds and their habitats. Also, this programme would be significant for the studies concerning the construction of various facilities (e.g. wind turbines). One of the important points of the development programme is to mobilize international cooperation and projects to solve current problems

The Scops Owl is a regular nesting species in the coastal areas of Croatia, but during the second half of the 20'th century its populations declined considerably. There are no data available about the size of the population breeding on the island of Solta, thus we count them them acorrding to calling individuals, berween 21 and 30 May 2008. The surveys were made in 8 settlements, between 21.00-23.00h each night. In total, 13 birds were heard calling at six localities: Maslinica, Donje Selo, area 2 km west of Donje Selo, Srednje Selo, Grohote, Rogac and Gornje Selo.
