Abstract Remains of at least three species large aegypiine vultures from early Palaeolithic and Iberomaurusian Ifri n’Ammar, Morocco are the first substantial fossil record these taxa in Maghreb. They can be tentatively referred to two extant Aegypius monachus (Cinereous Vulture) Gyps fulvus (Griffon Vulture), extinct melitensis . Few fragments remarkably bones may belong especially specimens A...

The success of reintroduction programs greatly depends on the amount of mortality and dispersal of the released individuals. Although local environmental pressures are likely to play an important role in these processes, they have rarely been investigated because of the lack of spatial replicates of reintroduction. In the present study, we analyzed a 25-year data set encompassing 272 individual...

Little is known about the spatial ecology and ranging behaviour of vultures in Europe. In this paper we used GPS satellite telemetry to assess home-ranges of eight non-breeding Eurasian Griffon Vultures in Spain, trying to answer the main questions on when (i.e. the time of the day), how far (i.e. hourly and daily distances) and where vultures range (i.e. home-range size). Results indicated tha...

Eulemur fulvus rufus has been described as having stable multi-male/multi-female groups, a male-biased sex ratio, and female philopatry. However, in a 16-year study of this subspecies we documented a great deal of demographic change as several groups permanently fissioned, some groups disappeared, and new groups formed. We split the dataset into two periods, 1988 to 1993 and 1994 to 2003, which...

Behavioral flexibility that requires behavioral inhibition has important fitness consequences. One task commonly used to assess behavioral inhibition is the reverse-reward task in which the subject is rewarded by the non selected items. Lemurs were tested for their ability to solve the qualitative version of the reverse-reward task with the choice between identical quantities of different food ...

The current study analyses and presents the results of ten-year establishment phase Griffon Vulture ( Gyps fulvus ) local re-introduction in Vrachanski Balkan Nature Park, north-western Bulgaria. Between 2010 2020, 61 rehabilitated captive-bred Vultures from Spain, France several European zoos were released an acclimatisation aviary. first successful breeding wild was reported 2015. Thus, speci...
