Assessing reintroduction outcome: comparison of the juvenile post-fledging dependence period between wild and reintroduced Bonelli’s eagles in two Mediterranean islands
Abstract Islands are key areas for biodiversity; however, they are extremely sensitive to anthropic actions. This has led to local species extinctions, especially large predators such as raptors. Consequently, reintroduction and conservation projects aimed at reversing population decline of endangered species have recently gained popularity. Nevertheless, their relatively elevated cost and chance of failure make them controversial, hence assessing their effectiveness is essential. Within the early stages of raptors, the post-fledging dependency period (PFDP) is the one in which individuals must face dangers without having completely developed their skills. Thereby, comparing PFDP patterns c…
SUCCESSFUL FOSTERING OF A CAPTIVE-BORN EGYPTIAN VULTURE (NEOPHRON PERCNOPTERUS) IN SICILY
Successful fostering of the Endangered Egypian vulture was implemeted in 2003 in 2 sites and successfully delivered.The two Egyptian Vulture wild nestlings and the foster nestling were weighed and banded. On 11 August 2003, the two wild juveniles left their nest at 0700 H, followed by the fostered young at 0930 H. One day after fledging, the three young flew back into the nest and in the following days returned to the nest at various times. We were able to track the family in the surrounding area until 28 August 2003. Dispersal from the breeding site occurred at the end of August, the usual period for this population. Our fostering experiment seemed successful; both foster parents and the a…
