Prioritizing renewable energy generation over the conservation of natural habitats and species on a large spatial scale, leads to the paradox of impacting biodiversity to mitigate climate change. In this study, we aim at quantifying the long-term demographic impact of the excess mortality caused by collisions with wind turbines on the populations o...

Natal dispersal is a crucial period for raptors with serious implications for individuals’ survival and population demography. In this study we analyzed data from 18 GPS-tracked golden eagles in order to describe their dispersal ecology in northern Greece, where the species feeds mostly on tortoises. Young eagles in our population dispersed at 176...

Climate change during the Quaternary period significantly influenced the distribution of Western Palearctic birds, favouring cold- and dry-adapted species. Conversely, warm-related species were restricted to glacial refugia of Southern Europe and North Africa. The lanner falcon (Falco biarmicus) is a polytypic species found in Afro-tropical and Med...

Wind harnessing is a fast-developing and cost-effective Renewable Energy Source, but the land impacts of wind power stations are often overlooked or underestimated. We digitized land take, i.e., the generation of artificial land, derived from 90 wind power stations in Greece constructed between 2002 and 2020 (1.2 GW). We found substantial land take...

In territorial raptors, breeding performance and foraging behaviour are affected by territory characteristics as the abundance and availability of different prey species varies between habitats. In this study, we examined the diet of two White-tailed Eagle pairs, occupying neighbouring territories in two adjacent inland lakes in Northern Greece. We...

Golden Eagles are resident in Greece and known to feed mainly on tortoises when breeding. However, information on alternative prey is scarce, especially during the tortoise brumation, that roughly coincides with the eagles’ non-breeding season. We analyzed 827 prey items collected from 12 territories over five territory years and 84 records of eagl...

This international meeting took place in the Holy City of Messolonghi (NW Greece) in December 2018 aiming to set up the baseline for the beginning of constructive network cooperation and in particular: 1) Close cooperation of all experts on vulture conservation in the Balkans. 2) Exchange of experience and know-how between scientists on vultures’ e...

The Convention of Migratory Species aims to protect migratory animals throughout their range, but efficient mitigation of threats facing migratory birds is hindered by poor knowledge about the magnitude and geographic range of threats. We used an expert assessment to prioritise which threats to mitigate in 13 countries along the eastern Mediterrane...

The Eurasian Griffon Vulture Gyps fulvus is a large Palearctic, Indohimalayan and Afrotropical Old-World vulture. The species’ range is vast, encompassing territories from the Pyrenees to the Himalayas. We reviewed and analysed a long-term data set for Griffon Vulture in the Balkans to estimate the change in its population size and range between 19...

Millions of large soaring birds migrate from the Palaearctic to Africa every year, and follow distinct flyways around the Mediterranean Sea. While there is conservation concern for many long-distance migratory bird populations, the magnitude and geographic range of threats affecting birds along flyways are poorly known, which complicates efficient...

An immature male marsh harrier (Circus aeuginosus) was trapped in late January, 2019 in the vicinity of the Evros Delta and fitted with GPS/GSM transmitter. Its home range encompassed an area of 146.2 km2 (95% MCP), and 50% 5.6 km2. MCP estimates showed a high monthly contraction of the home range (for 95% February=153.1 km2, March=44.7km2, April=2...

The biodiversity of cultural landscapes is a new scientific topic, as different species are closely linked to preindustrial land uses. We monitored a juvenile Griffon vulture with a GPS/GSM to study crucial areas for vulture conservation in the Balkans. In this work we present data for one year. The bird spent the first 2 months on Pindos mountain...

Vultures and eagles are large and impressive raptors that have a special role in the symbolic lore of local communities worldwide. We examine species folk names, everyday aphorisms, place names, local stories, ceremonies and folklore in modern Greece to demonstrate ways local communities conceptualize emblematic raptor species. As populations of th...

First shot at looking at the potential impact of WFs on the Golden Eagles in N Greece.

The Red-backed shrike (Lanius collurio) is a small passerine bird that prefers ecotones. It nests in a variety of habitats in rural and semi-rural areas, pastureland, field margins, natural or improved grassland, as well as mountains at very high altitude above the tree line, if grassland is mixed with trees and scrubs. We studied the reproductive...

The Golden Eagle (Aquila chrysaetos) is a large raptor with no natural predators, low breeding rates, deferred maturity, long life expectancy and is a protected species in Greece and the EU. To better understand the threats facing the specie’s populations we collected all available information for mortality (and admission in wildlife hospitals) fro...

Electrocution was identified as one of the main threats for the steeply declining Balkan population of the Egyptian vulture. To mitigate the threat by providing relevant information for insulation of the most dangerous pylons for vultures, mapping and risk assessment of electricity pylons were conducted in active and recent breeding territories of...

The Egyptian Vulture has been classified as ‘Endangered’ due to a rapid population decline in India and long term declines in Europe and Africa. Although the species has been reported to be declining in Eastern Europe, no quantitative assessment of the magnitude or the causes for population declines are available. We used monitoring data from the B...

We used phenotypic characteristics to identify individual birds in the remaining population of Egyptian Vultures in Greece. Every year from 2012 to 2015, facial markings and plumage patterns of birds were obtained from photographs of individuals or were drawn, as detailed as possible, on blank silhouettes of Egyptian Vulture when observation condit...

The need to preserve biodiversity in constantly changing landscapes in Europe has led to the designation of the Natura 2000 network and the need for a closer examination of species distributions and requirements within each site for the implementation of effective conservation measures. In this study we examine two passerine species, L. arborea and...

Executive summary Illegal actions in human behaviour such as that of illicit poisoning, which arises from human–wildlife conflicts threatens both the sustainable management of ecosystems and the conservation of biodiversity. Even though vultures aren't themselves target species for poisoning they are extremely vulnerable because they are scavenger...

Rationale In this session we seek to illustrate some of the work being undertaken across the globe by researchers and indigenous people with an interest in birds, people, cultures and the land and environments that they share. A number of themes have emerged from the recent renewed interest and concentration on ethnoornithology, including: the appl...

Ο Ασπροπάρης (Neophron percnopterus) αποτελούσε το κοινότερο είδος γύπα της χώρας, όπου μέχρι την δεκαετία του 1980 αριθμούσε τοπικά πάνω από 180 άτομα (π.χ. Μετέωρα). Τις δύο τελευταίες δεκαετίες παρουσιάζει δραματική μείωση σε όλες τις Βαλκανικές χώρες (Αλβανία, FYROM, Βουλγαρία), με συνολικό πληθυσμό σήμερα μικρότερο των 100 ζευγαριών. Στην εθνι...

“Presence of Vultures and other carrion eating birds in the artificial feeding site, on mt Pinovo, Aridea, N Greece”.

In order to establish an experimental feeding place for raptors and vultures at Tzena-Pinovo Mountain, northern Greece, a special method was applied and testified. Tzena-Pinovo Mountain is one of the richest areas for raptors in Greece. Three Vulture species including Bearded Vulture (Gypaetus barbatus) and two Aquila species breed or are present d...
