Can supplementary feeding increase predation or parasitism?
A replicated study in dry scrubland on Fuerteventura, Canary Islands, Spain, in spring 1996 Cortés-Avizanda et al. 2009), found that artificial nests were more likely to be predated when they were within 200 m of a carcase (both naturally-occurring and supplied to a vulture ‘restaurant’), compared to more distant nests. A total of 312 nests were laid in 12 lines. Nest predation occurred in 67% of lines, with a maximum of 92% of nests on a line being predated. The restaurant was supplied with approximately 200 kg/week of goat and pig carcasses whilst naturally occurring carcasses consisted of one goat and one yellow-legged gull Larus michaellis. Nests imitated either those of lesser short-toed larks Calandrella refescens or cream-coloured coursers Cursorius cursor and contained two Japanese quail Cortunix japonica eggs.
