摘    要:2006年3~5月,收集南充高坪机场草地和周围松林越冬期短耳鸮(Asio flammeus)的食团,进行食性分析。在805个完整食团和一些零碎的食团中,小型兽类是短耳食物组成的主要成分,占98.4%,其中四川短尾(Anourosorex squamipes)所占比例最高,为97.2%。通过调查短耳鸮的食团在南充高坪机场草地里的分布情况,分析短耳v在机场草地的栖息地选择,发现短耳鸮并没有选择草高和密集的区域作为栖息场所,而高20cm左右的白茅(Imperata cylindrical)丛是短耳最喜欢栖息的场所。

关 键 词:短耳鸮  越冬习性  食性分析  高坪机场

Abstract:Pellets from Short-eared Owls(Asio flammeus) were collected and analyzed for preyed remains during March-May 2006 in the Gaoping Airport of Nanchong and near pine forest.Small mammals are the main prey of Short-eared Owls(98.4% of the total frequency),in which 97.2% is Anourosorex squamipes in the 805 whole pellets and some pellet fragments.The roosting habits of Short-eared Owls were determined by the distribution of pellets from Short-eared Owls in the same time.The owl prefers to roost in the fields of Imperata cylindrical(about 20 cm high) than the taller,denser grass.
Keywords:Asio flammeus  Diet analysis  Winter habit  Gaoping airport
