| 中文摘要: |
| 2012-2014年3-6月,在广西弄岗地区记录到3例八声杜鹃(Cacomantis merulinus)的寄生繁殖,其中2例寄生于栗头缝叶莺(Orthotomus cuculatus)的巢,1例寄生于黑喉缝叶莺(O. atrogularis)。栗头缝叶莺为八声杜鹃寄主的首次报道,而两种缝叶莺寄主均首次在中国记录到被八声杜鹃寄生。八声杜鹃的卵大小和重量都显著大于两种缝叶莺的卵。光谱分析表明,八声杜鹃的卵在背景色和斑点上均与两种缝叶莺寄主有差异。 |
| 英文摘要: |
| During the breeding season from March to July in 2012-2014, two nests (1.4% of parasitism rate, n=142) of the Mountain Tailorbird (Orthotomus cuculatus) and one nest (10%, n=10) of the Dark-necked Tailorbird (O. atrogularis) were found to be parasitized by the Plaintive Cuckoo (Cacomantis merulinus) in Nonggang area, Guangxi, Southwestern China. The Mountain Tailorbird was firstly recorded as host species by Plaintive Cuckoo, and both the two tailorbird species were firstly recorded as Plaintive Cuckoo hosts in China. The egg mass and volume of the Plaintive Cuckoo were significantly larger than those of the two tailorbird hosts. Spectra analysis of egg reflectance showed that both background color and spot markings of the cuckoo eggs were much different from its two tailorbird hosts. |
