Foster eggs or chicks of raptors with wild conspecifics
A small study at a lake in Pennsylvania, USA, in 1988 (Rymon 1990), found that two osprey Pandion halieatus chicks were successfully adopted by a breeding pair that had lost their two chicks to predation. The foster chicks were 5.5 weeks old and were placed in the nest two weeks after the original young were last seen and were accepted later that day. No information is provided on fledging or subsequent survival but the author notes that “the nestlings were fed well and protected by their foster parents throughout the nesting period”.
