摘要
2016和2017年,在广东鼎湖山国家级自然保护区及广东同乐大山省级自然保护区,用行为观察法和微型摄像机记录了淡眉雀鹛(Alcippe hueti)、红嘴相思鸟(Leiothrix lutea)、栗颈凤鹛(Staphida torqueola)和褐顶雀鹛(Schoeniparus brunneus)等12种鸟类的繁殖习性.描述了它们的巢特征、卵重、卵大小、窝卵数及育雏等繁殖参数.研究发现:1)与历史数据相比,经过近30年的时间,在广东鼎湖山的淡眉雀鹛筑巢高度增加;2)与国内其他地区相比,红嘴相思鸟的筑巢高度也增加;3)发现乌鹃(Surniculus lugubris)和棕腹鹰鹃(Hierococcyx nisicolor)将淡眉雀鹛巢中的淡眉雀鹛雏鸟移出巢外;4)发现淡眉雀鹛亲鸟将其巢中的鸟卵和雏鸟移出巢外.
Abstract
[Objectives]Monitoring nesting characteristics is one way to track the reproductive success of a species.[Methods]Based on personal observations and videos collected by micro-camera,we describe the nesting characteristics of Huet's Fulvetta Alcippe hueti,Red-billed Leiothrix Leiothrix lutea,Indochinese Yuhina Staphida torqueola,Dusky Fulvetta Schoeniparus brunneus,Rufous-capped Babbler Cyanoderma ruficeps,Streak-breasted Scimitar Babbler Pomatorhinus ruficollis,White-tailed Robin Myiomela leucura,Lesser Shortwing Brachypteryx leucophris,Mountain Bulbul Ixos mcclellandii,Red-whiskered Bulbul Pycnonotus jocosus,Black-throated Prinia Prinia atrogularis,and Yellow-bellied Prinia Prinia flaviventris(Fig.1).Surveys were conducted in Guangdong Dinghushan National Nature Reserve and Guangdong Tongledashan Province Nature Reserve between 2016-2017.Nesting characteristics examined include nest composition,nest height,egg weight,egg size,clutch size,and incubation period.[Results]Based on these characteristics we found:1)Huet's Fulvetta in Dinghushan,nest height has increased compared to our results from 1989;2)compared to other studies in China,Red-billed Leiothrix in our study had higher nests;3)this was the first report that Square-tailed Drongo-Cuckoo Surniculus lugubris and Whistling Hawk-cuckoo Hierococcyx nisicolor removed fledglings of Huet's Fulvetta.4)We also found the behavior of removing egg and nestlings by adult Huet's Fulvetta.[Conclusion]Our results provide the basis for the future research on the life-history strategies of birds in Guangdong.
