| Résumé : | The responses of wintering cranes from southwestern Spain (Serena region) to potential predators were studied. Three different behavior patterns were observed when the predators appeared: flight, forming of dense groups on the ground as well as continuation of activity (no reaction). Flight response was higher when eagles attacked, group forming was induced by griffon vulture, raven, and red fox, while the presence of red kite was ignored. |
