Stratégies de prospection alimentaire des vautours fauves (Gyps fulvus) et conséquences sur la gestion anthropiques des ressources alimentaires.

Foraging strategies of Griffon vultures (Gyps fulvus) and consequences on food resources management.

Abstract

As a conservation tool, supplementary feeding programs are widely applied on a large range of species, from songbirds to raptors – even large predators such as the Iberian Lynx (Lynx pardinus).  Directed to populations whose productivity or survival is thought to be limited by food scarcity, supplementary feeding is likely to bring positive benefits but also negative ones (e.g. spread of diseases, changes in territorial behavior, reduced reproductive success). Thus, carcass provisioning to support scavengers can be a controversial practice, with potential impacts at the individual and population levels.

While scavengers have supposedly evolved to search for unpredictable resources, centralized feeding stations are likely to promote non-natural behaviors. Making food resources artificially, supplementary feeding may represent an ecological trap to birds. Understanding space use of free-living scavengers depending – or not - on anthropogenic management is essential to guide future conservation planning.

The aim of my PhD is to better understand and to compare the foraging strategies of griffon vultures from two contrated regions. While in the Grands Causses, supplementary feeding stations were established to sustain the reintroduced population in the 1980s, the native French Pyrenean population mainly depends on extensive pastoralism. To understand how predictability of food resources may affect foraging behaviors of vultures, my plans are: 1) to compare home ranges and space use of individuals in both regions; 2) to quantifiy the level of routine in the movement behaviours of vultures from the Grands Causses where food is predictable in space even time.
