  1. Release captive-bred individuals into the wild to restore or augment wild populations of vultures

    Further analysis of the reintroduction programme discussed in Sarrazin et al. 1994 and Sarrazin et al. 1996 found that the breeding population of griffon vultures Gyps fulvus in the release area in southern France increased from approximately 13 pairs in 1987 to 130 breeding pairs in 2005, following the release of 61 captive-bred birds (Bose & Sarrazin 2007). Eleven young adult (between five and nine years old) releases fed their chicks at a lower rate than eight wild-bred birds, but in all age classes there was no difference in feeding rates or dominance of released, compared with wild-bred birds.
