摘　　要：1999—2019年的9—10月在长岛大黑山岛进行猛禽网捕环志,共环志猛禽43363只,隶属3目5科39种,占山东猛禽物种数量的84.78%,占全国猛禽物种数量的41.00%。经年的环志种类相对稳定,但环志总量呈下降趋势;优势种为红角鸮(Otus scops)、日本松雀鹰(Accipiter gularis)、雀鹰(Accipiter nisus)、长耳鸮(Asio otus)和苍鹰(Accipiter gentilis),其中红角鸮和日本松雀鹰的环志总数最多,分别占总数的37.9%和29.8%。在过去的20年间,除红角鸮每年的环志数量呈波动外,其余4种优势种的数量均呈明显的下降趋势。连续监测表明,日本松雀鹰秋季迁徙高峰期每10年推迟2—8 d。虽然《中国脊椎动物红色名录》中定为无危的日本松雀鹰和雀鹰环志量仍相对较高,但经年的下降幅度远大于苍鹰等近危种。以上结果或许与栖息地破坏、食物短缺、非法猎捕以及气候变化等密切相关,应引起持续重视并加强监测。The species and number of raptors in Changdao,Shandong Province were analyzed during 1999-2019.Totally 43,363 individuals were banded.Totally 39 raptor species of five families and three orders were recorded,accounting for 84.78%of the total raptor species in Shandong Province and 41.00%of the total raptor species in China.There were five dominant species,i.e.,Otus scops,Accipiter gularis,Accipiter nisus,Asio otus and Accipiter gentilis,of which Otus scops and Accipiter gularis accounted for 37.9%and 29.8%,respectively,of total banded individuals.In the past two decades,the annual banded number of Otus scops was fluctuant,while the number of the rest four dominant species declined significantly.The most prominent reasons causing raptor population declines are habitat destruction,food shortage,hunting and climate change.The peak migration of Accipiter gularis in fall was delayed by two to eight days every decade.The numbers of banded Accipiter gularis and Accipiter nisus were still large,but the drop was large as well,which should be paid great attention and continuous monitoring is needed.
