| 中文摘要: |
| 部分鸟类在繁殖过程中，为避免被捕食、减少繁殖投入等而选择占用其他鸟类的巢。2014 ~ 2016年每年的4 ~ 8月，在吉林向海国家级自然保护区记录到4种占用喜鹊巢进行繁殖的鸟类，其中绿头鸭（Anas platyrhynchos）8巢，纵纹腹小鸮（Athene noctua）4巢，长耳鸮（Aiso otus）5巢，麻雀（Passer montanus）6巢。大部分（82.6%）为利用喜鹊的废弃旧巢，而绿头鸭（1巢）、长耳鸮（2巢）和纵纹腹小鸮（1巢）少数侵占喜鹊当年新建的巢。 |
| 英文摘要: |
| A suitable nest-site for reproduction is limited and thus some species may take over active/used nests and/or nest holes of other species for breeding. During the breeding season (April to August) in 2014﹣2016, 23 cases of breeding birds using Common Magpie (Pica pica) nests in Xianghai National Nature Reserve, Jilin, China, were reported in this study. Four bird species, namely Long-eared Owl (Aiso otus, 5 nests) (Fig. 1), Mallard (Anas platyrhynchos, 8 nests), Little Owl (Athene noctua, 4 nests), and Tree Sparrow (Passer montanus, 6 nests) (Fig. 2) were found in magpie nests. Among them, four cases (17.4%) were nest usurpation. Nest usurpation occurred mainly in the sparse elm forest in West Songnen Plain, which is inhabited by Magpies and usurped birds. The nest height, tree height, tree diameter at breast height, nest direction, and nest width and nest depth of four usurpers were recorded (Table 1﹣4). Larger birds like Long-eared Owls and Mallards usually dismantled part or rooftop of nests in using. Owls prefer nests in higher trees than other usurpers while Mallards usurped Magpie nests close to water. |
