| 中文摘要: |
| 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,小型兽类是短耳鸮食物组成的主要成分,占98.4%,其中四川短尾鼩 (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,分析短耳鸮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20 cm左右的白茅(Imperata cylindrical)丛是短耳鸮最喜欢栖息的场所。 |
| 英文摘要: |
| 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. |
