One can only be accepted by the association governing hawk-raising if the bird is not only alive after 3-5 years, but still has glossy feathers, is highly spirited, and has not been in any way "maltreated." Only then is one considered qualified to get permission to raise other varieties which are larger or harder to handle.
如此養三、五年，沒把鷹養死，且羽翼光滑、精神飽滿、未遭「虐待」，才能被養鷹學會與指導顧問認可，也才有資格升級，被允許養紅尾鷲等體型較大、或較不易照養的種類。
