摘　　要：黑耳鸢(Milvus migrans lineatus)属于中型猛禽,分布广泛,是国家二级保护野生动物。上海动物园始建于1954年,前身为西郊公园。饲养黑耳鸢采用2014年新改建的仿生态笼舍,坐北朝南,占地约750 m^(2),高达17 m。黑耳鸢在繁殖时雏鸟发生种内争斗,为了提高雏鸟成活率,将上海动物园自然孵化出壳的2只雏鸟中较弱的雏鸟取出,进行了人工育雏。该雏鸟由于饲料钙磷比例失衡,腿无力,无法站立及正常行走,后调整饲料钙磷比例、改善了光照和饲养管理,成功恢复该雏鸟腿部功能,使其顺利成长。在此之前上海动物园尚未有人工育雏过猛禽,此次育雏经历为今后的工作累积了十分宝贵的经验。Black eared kite(Milvus migrans lineatus),as a second level protected wild animal in china,is a medium-sized bird of prey in the family Accipitridae,and thought to be the world’s most abundant species of Accipitridae.The Shanghai Zoo,formerly known as Western suburbs Park,was founded in 1954.Breeding house for Black eared kites was renovated ecologically in 2014,up to 17 meters high,with windows facing south and back facing north,covering an area of approximately 750 square meters.The intra species fighting among the chicks of Black eared kites during breeding may cause serious injuries.In order to increase the captive population of this species,the weaker of the two chicks that were hatched naturally was separated for artificial breeding.The chick was too fatigue to stand and walk normally with leg weakness due to imbalance in calcium phosphorus ratio in feed.Through optimizing the feed calcium phosphorus ratio and feeding strategy,the leg function of the chick got well recovered.Practicing artificial raising raptors in Shanghai Zoo offered a more complete view of brooding for raptors,and accumulated valuable experience for future work.
