“…By contrast, only the use of body parts (81% respondents) was perceived as a major threat at high elevations. As in our study, anthropogenic threats were identified as having a strong influence on territory abandonment by Bearded Vultures in southern Africa (Krüger et al 2015) and the population decline in the Pyrenees (Margalida et al 2008, Margalida 2012 and Balkans (Parvanov et al 2018). Medium-sized domestic and wild ungulates are the most preferred prey items of Bearded Vultures (Brown andPlug 1990, Margalida et al 2009).…”

“…Poisoning is considered to be one of the greatest threats to vultures in Europe [ 9 , 11 , 28 , 31 , 53 , 54 ]. Our results showed that poisoning is the most crucial factor negatively affecting the population of Eurasian Black Vulture in the area of the DLS-NP resulting in high extinction probabilities under medium (94.8% possibility of extinction) and high (100% possibility of extinction) poisoning levels.…”

“…Our results showed that poisoning is the most crucial factor negatively affecting the population of Eurasian Black Vulture in the area of the DLS-NP resulting in high extinction probabilities under medium (94.8% possibility of extinction) and high (100% possibility of extinction) poisoning levels. In southeast Europe, massive poisoning events resulted in many vulture deaths [ 53 , 55 ]. Our results suggest the absence of control may lead to extirpation of the species from the area.…”

“…The extensive use of illegal poison baits for the eradication of carnivores (including wolves and dogs) is the main cause of vulture poisoning in the Balkans [ 53 , 55 ]. The reappearance of wolves during the last decade resulted in the occurrence of carcasses accessible to vultures, which in turn were used as poison baits by different social groups [ 56 ], resulting in the death of the scavenger species [ 53 , 55 ]. Adult mortality is a crucial factor affecting necrophagous birds and the sustainability of their populations [ 57 ].…”

“…Outside Greek borders, traditional stock rearing systems exist and favor the presence of different necrophagous species, such as Griffon and Egyptian Vultures [ 58 ]. On the other hand, poisoning events outside the Greek borders are quite common and the exposure of vultures to poisoned baits is relatively high [ 53 ]. The establishment of an SFS network through Thrace and Bulgaria would facilitate the safer dispersal of the species and help to eliminate poisoning events [ 53 ].…”

The Eurasian Black Vulture is a globally threatened raptor that in Southeast Europe only occurs in an isolated population in Greece. We examined the population viability for the species under demographic fluctuations and conservation scenarios. The current population showed no possibility of extinction for the next 100 years. However, simulated scenarios showed that the most important factor affecting the viability of the species was medium and high poisoning, leading to 94.8% and 100% probability of extinction, respectively. Furthermore, high reduction of supplementary feeding highlighted an 18.6% extinction possibility. Also, a high increase of wind farms in the area may result in 17.4% extinction possibility. Additionally, the non-establishment of the feeding station in 1987 in the study area would have resulted in an extinction risk of 7%. The species can be translocated to the Olympus National Park by releasing 80 juveniles over 10 years. The implementation of the conservation scenarios concerning the establishment of a supplementary feeding site network, and the reintroduction of the Eurasian Black Vulture in its historic range, along with the elimination of threats posed by poisoning, low food availability, and wind farms would increase the probability of the species persistence and allow the population to become a source for dispersal across Southeast Europe.

Due to an abundance and diversity of vultures, Nepal is one of the most important countries for vulture conservation. Within Nepal, the Pokhara Valley is especially significant. We examine the distribution of vultures within the Pokhara Valley by conducting counts at 11 potential feeding or roosting sites using point count method. We further surveyed people of the valley regarding their perception of vulture ecology and conservation, knowledge of diclofenac use within the valley, and burial of livestock carcasses. We detected eight species of vultures, four of which are currently threatened with extinction. White‐rumped vulture Gyps bengalensis, Egyptian vulture Nephron percnopterus, and Himalayan vulture G. himalayensis were the most abundant. Almost all respondents (98%) had sighted the vultures in the wild. Formally educated respondents reported seeing vultures’ slightly more than nonformally educated respondents. Fifty‐eight percent respondents suspected habitat loss was the major threat for the vulture population decline in Pokhara Valley, and 97% respondents were not aware of any diclofenac use. The knowledge of vultures in people with different age groups suggests a more awareness programs are needed for local people, especially those who carry out animal husbandry and provide livestock to the vulture restaurant.
