  1. Provide supplementary food for vultures to increase reproductive success

    A before-and-after study in a woodland mosaic in north-eastern Greece (Vlachos et al. 1999) found that, following the establishment of a feeding station in 1987, the number of European black (cinereous) vultures Aegypius monachus overwintering and breeding in the study area increased significantly (overwintering population of 24 in 1984 vs. 59 in 1997; breeding population of 10 pairs in 1984 vs. 21 in 1997). The proportion of pairs successfully fledging young varied considerably but also increased over the study period, as did the number of fledglings produced annually (40-55% fledging success in 1984-1986, average of 47% success and 5 young fledged/year vs. 50-95% and an average of 75% and 12 young/year in 1987-1997). The feeding station was supplied year-round with cattle or horse carcasses every two weeks or so and was protected by a fence to deter mammalian scavengers.
