The summary of data from range countries estimates the population size of the Eastern Imperial Eagle (Aquila heliaca Savigny 1809) in Europe at 1800-2200 pairs, which reflects a significant increase compared to previous estimations. Also, there has been a significant increase in the number of known breeding pairs reaching 1134 known territories. Recent intensified surveys on distribution and abundance in key regions (Russia, Kazakhstan, European Turkey, Macedonia, Azerbaijan), as well as the currently recorded stabilization and increase of the entire Carpathian population makes a more precise status assessment of Eastern Imperial Eagles in Europe possible. Although in recent years the population of Eastern Imperial Eagles in some Balkan countries has been studied more intensively, further detailed research is still needed in potential breeding areas in SE Europe. In the region of Thrace (Bulgaria and European Turkey) the Eastern Imperial Eagle population was found to be more abundant, while population decline has been recorded in Greece, Macedonia, and Serbia. Russia and Kazakhstan hold the largest populations of the Eastern Imperial Eagle in Europe, which seem to be stable. Between 2000 and 2010 a sevenfold increase was documented in the number of known breeding pairs of Eastern Imperial Eagles in Europe. Based on the results of regional surveys in range countries, the Eastern Imperial Eagle population status in Europe can be considered to be stable and probably increasing.

Recent years have seen considerable progress in applying single nucleotide polymorphisms (SNPs) to population genetics studies. However, relatively few have attempted to use them to study the genetic differentiation of wild bird populations and none have examined possible differences of exonic and intronic SNPs in these studies. Here, using 144 SNPs, we examined population genetic differentiation in the saker falcon (Falco cherrug) across Eurasia. The position of each SNP was verified using the recently sequenced saker genome with 108 SNPs positioned within the introns of 10 fragments and 36 SNPs in the exons of six genes, comprising MHC, MC1R and four others. In contrast to intronic SNPs, both Bayesian clustering and principal component analyses using exonic SNPs consistently revealed two genetic clusters, within which the least admixed individuals were found in Europe/central Asia and Qinghai (China), respectively. Pairwise D analysis for exonic SNPs showed that the two populations were significantly differentiated and between the two clusters the frequencies of five SNP markers were inferred to be influenced by selection. Central Eurasian populations clustered in as intermediate between the two main groups, consistent with their geographic position. But the westernmost populations of central Europe showed evidence of demographic isolation. Our work highlights the importance of functional exonic SNPs for studying population genetic pattern in a widespread avian species. © 2015 Macmillan Publishers Limited All rights reserved.

McDonald and Griffith (2011) raise important points in their critique of reliance on feathers as a source of DNA for scientific research. Although those authors are right about many details, their one-size-fits all approach (i.e. prescribing blood draws for avian DNA analyses) obscures bigger picture issues that are of extraordinary relevance to avian biology. We introduce four points to provide alternative perspectives on their commentary. In particular, we feel that a) scientific goals should determine methodologies; b) stress to animals is context specific and blood sampling is not always less stressful to birds than feather plucking; c) feather DNA is too valuable to be ignored, especially when coupled with other analyses that require feathers; and d) logistical and other concerns often preclude blood sampling. A one size fits all approach to science is generally short-sighted, be it in regard to the collection of genetic or other samples from birds, or to a suite of other research problems. © 2012 The Authors.

Halting biodiversity loss is a critical aim for the forthcoming decades, but is hindered by the gap between research and practice. Bridging this gap is a significant challenge in the countries of Central and Eastern Europe, where, compared to Western European countries, biodiversity is higher but the research budget is lower. Approaches to address bridging this gap include participatory research prioritizing exercises. These demand-driven collaborative ranking processes have proven to be a useful tool in providing a research agenda derived from a review of critical challenges based on stakeholder engagement. However, for research agendas to be effectively realized, they are best developed and implemented at the operative level of research financing and implementation. This paper shows the process and the outcome of an exercise conducted in Hungary aiming to compile the most important conservation research questions at the country-level and outlines a set of further measures and tools required for dissemination and advocacy for the research agenda. During the process 792 research questions were collated from conservation practitioners and natural resource managers based on interviews and via an online questionnaire; the final 50 most important questions were identified by practitioners and policy makers during an expert workshop. Questions are embedded in global and EU biodiversity targets and imply a pragmatic approach with the aim of identifying research that supports policy- and decision-making regarding habitat management, land-use and regional development, while also focussing on conflicting issues. The outcome of the process includes the potential for lobbying, therefore post-publication activities and dissemination strategies are outlined as an integrated part of the exercise. © 2015 Elsevier GmbH.

In order to stop the decline of Hungarian meadow viper Vipera ursinii rakosiensis, in 2004 MME BirdLife Hungary together with national parks and Budapest Zoo started a complex conservation programme, supported by the European Union LIFE-Nature fund. The Hungarian Meadow Viper Conservation Centre was established with 16 adult individuals, collected from six different populations. By 2013 the number of vipers bred reached c. 1700 individuals. First reintroductions took place in March 2010, with 30 adult snakes released into a reconstructed habitat in Kiskunság National Park. By 2013, a total of 240 snakes had been released into three locations. Snakes were released by relocating the animals in the artificial burrows they used in the semi-natural terrariums at the Hungarian Meadow Viper Conservation Centre. At the release sites vipers were recorded 255 times during post-release monitoring, and 69 individuals were identified. Eighteen of the observed ♀♀ were gravid, and ten juvenile or subadult individuals were documented. In order to develop a remote-tracking method, pre-programmed radio-tags with a detection range of 200-300m were surgically implanted into the abdomens of 16 vipers. These tags also operated as temperature loggers, recording data every 5 minutes for one year. Zoos play an important role in communicating the results of this captive-breeding and release programme. Exhibits of live Hungarian meadow vipers are located at Budapest Zoo and Schönbrunn Zoo in Vienna, Austria, and there are information points about the species located in all Hungarian zoos. © 2014 The Zoological Society of London.

The Eastern Imperial Eagle (Aquila heliaca Savigny 1809) reaches the western border of its range in the Carpathian Basin, which is the largest known population outside Russia and Kazakhstan. An increasing trend of this population in Hungary and also in the nearby areas of Slovakia has been reported since the 1980's, when the number of breeding pairs supposedly reached the historical minimum. In this study we evaluated the dynamics of the Hungarian Imperial Eagle population between 2001 and 2009. As a result of the continuous increase of the population the monitoring program revealed 105 nesting pairs by 2009. While an expansion of the breeding area towards lowland agricultural habitats was observed, the ratio of pairs inhabiting the historical mountainous breeding habitats decreased from 50 % to only 15 % during the study period. The frequency of the two- and three-chick broods in respect to single-chick broods increased in comparison to the 1980-2000 period showing a higher average annual productivity of the population (1.15 fledglings per nesting pair). Besides the favourable changes in population trend and productivity, the area expansion in the recently occupied lowland habitats also raised several new threats to the population, such as the increased number of illegal poisoning incidents and more frequent collisions with vehicles.

Reproductive success of raptor species is significantly affected by the quantity and/or quality of available prey. In our study we analysed prey composition of breeding imperial eagles (Aquila heliaca) in East Hungary, where 434 nesting events in 81 different territories had been monitored between 1995 and 2004. We identified 1297 prey items originating from 43 bird and 16 mammalian species (532 and 764 specimens, respectively). Three prey species, the brown hare (Lepus europaeus), the hamster (Cricetus cricetus) and the pheasant (Phasianus colchicus), seem to have especially important role in the diet of imperial eagles in Hungary, although their relative frequencies varied greatly among different regions. We found that eagles were less productive in a region where hamster was the main prey (West Zemplén Mts) as compared to a recently colonized hare-dominated region (Heves Plain), suggesting that hares may provide a better food source than hamsters. The increase of game species in the diet of imperial eagles could generate hostility in hunters. Possible conflict between nature conservation and small-game management may be resolved by raising public awareness and by common projects to improve hare and pheasant habitats.

The foraging habitat selection of Red-footed Falcons (Falco vespertinus) was investigated in a characteristic Hungarian habitat between 2006-2008. Potentially available habitat types were assessed within a 10 km 2 study site with remote sensing technologies. Altogether 18 adult birds were equipped with tail-mount VHF radio-tags and individually followed until visual contact to record location and foraging behaviour. Foraging areas were assessed with 100% Minimum Convex Polygons (MCP), global Manly's selectivity measures were used to detect population level habitat preference, and the eigenanalysis of selection ratios was carried out to partition the variability in individual habitat preference. We found large individual variability in the extent of foraging areas. Females had significantly smaller foraging areas compared to males, while males at the largest colony had significantly larger foraging areas compared to males of the smaller colonies. Global Manley's selectivity measures showed that birds significantly avoided intertilled crops, water surface, woods and artificial surfaces. The eigenanalysis of selection ratios partitioned individual habitat selection rates into two distinct groups; the first using grasslands and alfalfa while the second group of birds preferring grasslands and cereals. Positive habitat preference towards arable habitat types, indicate that species specific conservation efforts of this declining raptor should also focus on agricultural land use practices.
