Modelling survival rates in the Cape GriffonGyps coprotheres,with emphasis on the effects of supplementary feeding

Relative contribution of local demography and immigration in the recovery of a geographically-isolated population of the endangered Egyptian vulture

“…In some contexts, supplementary feeding seem to have enhanced the survival of immature bird only (+ 60% for juvenile Cape griffons, Piper et al, 1999;+ 20% for pre-adult Bearded vultures, Oro et al, 2008). Whereas in other contexts, they appeared ineffective in reducing griffon vultures mortality which was caused by poisoning in Spain (Martínez-Abraín et al, 2012).…”

Intra-specific competition in foraging Griffon Vultures Gyps fulvus: 2. The influence of supplementary feeding management

“…HFS are very useful tools to restore endangered raptor populations (Friedman & Mundy 1983, Gende & Willson 1997, Piper et al 1999, González et al 2006. They are necessary in the long term for some populations at risk of poisoning to provide food free from contaminants (Gilbert et al 2007, Walters et al 2010.…”

Carrion ecology modelling for vulture conservation: are vulture restaurants needed to sustain the densest breeding population of theAfrican white‐backed vulture?

“…Thus the practice of providing supplementary resources is a common conservation tool (Piper, 2005, Piper et al, 1999. As these 'vulture restaurants' or 'feeding stations' can make carrion more predictable in space and time (Oro et al, 2008), there are implications for the ecosystem services and foraging behaviour of the species affected (Deygout et al, 2010, Monsarrat et al, 2013.…”
