  1. Foster eggs or chicks of vultures with wild conspecifics

    A small study on a farm in North Carolina, USA, in June 1975 (Stewart 1983) found that transferring a 35-40 day-old (American) black vulture Coragyps atratus chick from a nest that was about to be destroyed to a nest containing two 30-35 day-old chicks led to the successful rearing of the fostered chick. However, the smaller of the two chicks originally in the nest was neglected by its parents and died soon after the foster chick was introduced. No data on the fledging success or subsequent survival of the surviving chicks is provided.
