贵州宽阔水自然保护区小杜鹃对小鳞胸鹪鹛的巢寄生
Brood Parasitism on Pnoepyga pusilla by Cuculus poliocephalus in Kuankuoshui Nature Reserve, Guizhou, China

中文摘要：2015年4-8月,在贵州宽阔水国家级自然保护区记录到小杜鹃 Cuculus poliocephalus在小鳞胸鹪鹛 Pnoepyga pusilla巢中寄生繁殖。发现时小鳞胸鹪鹛已处于孵卵后期,巢内有1枚红棕色的小杜鹃寄生卵和3枚小鳞胸鹪鹛的白色卵。小杜鹃卵质量为2.55 g,体积2.72 cm 3,小鳞胸鹪鹛卵质量(1.64±0.16)g( n=7),体积(1.65±0.08)cm 3( n=7),两者的卵在颜色和大小上差别明显。光纤光谱仪对卵色的测量和分析结果表明,小鳞胸鹪鹛的卵色亮度显著高于小杜鹃,小杜鹃的卵为高度非模拟寄生卵。这是小鳞胸鹪鹛被小杜鹃寄生的第二例报道,说明其可能是小杜鹃的适宜寄主。
英文摘要：During the breeding season from April to August 2015, one case of brood parasitism on pygmy wren babbler ( Pnoepyga pusilla) by lesser cuckoo ( Cuculus poliocephalus) was observed in Kuankuoshui National Nature Reserve, Guizhou, southwestern China. The parasitized nest with one chocolate cuckoo egg and three white babbler host eggs were found at the late incubation period. The cuckoo egg mass was 2.55 g and egg volume was 2.72 cm 3, while the babblers' egg mass was 1.64 g±0.16 g and egg volume was 1.65 cm 3±0.08 cm 3 ( n=7). Egg reflectance analysis showed that egg hue and chroma of the pygmy wren babbler were significantly different with those of lesser cuckoo, and therefore lesser cuckoo will lay a highly non-mimetic egg in its babbler host's nest. This was the second report of interspecific brood parasitism on pygmy wren babbler by lesser cuckoo, and suggested that pygmy wren babbler may be one of the suitable hosts for lesser cuckoo. 2016,(35): 235-237 收稿日期：2015-12-03 DOI：10.11984/j.issn.1000-7083.20150385 分类号：Q959.7 基金项目：国家自然科学基金(No. 31272328, No. 31472013)资助项目 作者简介：邵玲, 女, 硕士研究生, 研究方向:鸟类行为生态, E-mail:532970553@qq.com *通讯作者：梁伟, E-mail:liangw@hainan.net 参考文献： 李桂垣. 1985. 四川资源动物志 第三卷 鸟类[M]. 成都: 四川科学技术出版社. 蒋迎昕, 梁伟, 杨灿朝, 等. 2006. 小杜鹃在强脚树莺巢中寄生繁殖[J]. 动物学杂志, 41(5): 31. 刘焕金, 苏化龙, 申守义, 等. 1988. 关帝山鹪鹩繁殖生态的初步研究[J]. 动物学杂志, 23(6): 8-12. 王鹏程, 杨艾琳, 张正旺, 等. 2016. 小杜鹃对小鳞胸鹪鹛的巢寄生[J]. 动物学杂志, 51(2): 319-322. 王众, 贾陈喜, 孙悦华. 2004. 中杜鹃寄生繁殖及雏鸟生长一例[J]. 动物学杂志, 39(1): 103-105. 杨灿朝, 蔡燕, 梁伟. 2010. 小杜鹃对强脚树莺的巢寄生及其卵色模拟[J]. 动物学研究, 41(5): 555-560. 杨灿朝, 蔡燕, 张淑萍, 等. 2009. 利用光纤光谱仪量化和分析鸟类的卵色[J]. 生态学杂志, 28(2): 346-349. 喻理飞, 谢双喜, 吴太伦. 2004. 宽阔水自然保护区综合科学考察集[C]. 贵阳: 贵州科技出版社. 约翰·马敬能, 卡伦·菲利普斯, 何芬奇. 2000. 中国鸟类野外手册[M]. 长沙: 湖南教育出版社. 赵正阶. 1985. 长白山鸟类志[M]. 长春: 吉林科学技术出版社.
