Current sanitarian regulations are not enough for avian scavengers' conservation

A scientific team has studied how the use of human-origin food resources, such as landfills and intensive livestock farms, by Eurasian griffon vultures can negatively impact their conservation.
These studies have been led by the Doñana Biological Station – CSIC, the University of Sevilla and the University Miguel Hernández of Elche with the collaboration of the University of Lisbon

Apex scavengers from different European populations converge at threatened savannah landscapes

An international scientific team found that “dehesas”, savannah-like systems from the southwest of the Iberian Peninsula, attract Eurasian griffon vultures from distant populations from Northern, Central and Southern Spain and Southern France, thanks to the traditional agro-grazing practices and rich wild ungulates populations.

Humans shape distribution and habitat use of an opportunistic scavenger

Research focused on evaluating how human food subsidies influence the foraging ecology of scavenger species is scarce but essential for elucidating their role in shaping behavioral patterns, population dynamics, and potential impacts on ecosystems. This study evaluates the potential role of humans in shaping the year?round distribution and habitat use of individuals from a typical scavenger species, the yellow?legged gull (Larus michahellis), breeding at southwestern Spain.

The use of roads in protected areas and its effects on avian scavenger guild

The expansion of road networks and the increase in traffic have emerged in recent years as key threats to the conservation of biodiversity. This is particularly concerning in many protected areas because the increase of recreational activities requiring the use of vehicles. Effects of roads and traffic within guild scenarios and ecological processes remain however poorly known. This study examined how road proximity and traffic intensity influence patterns of resource use in an Old-World...

Survival and breeding success in Egyptian vulture

In long-lived species, the age-, stage- and/or sex-dependent patterns of survival and reproduction determine the evolution of life history strategies, the shape of the reproductive value, and ultimately population dynamics. This study evaluates the combined effects of age and sex in recruitment, breeder survival and breeding success of the globally endangered Egyptian vulture.
