摘要: 灰腹噪鹛(Garrulax henrici)是中国的特有鸟种,也是噪鹛属中繁殖行为研究较少的物种之一。2016年4—7月,在西藏林芝西藏农牧学院内进行了灰腹噪鹛的繁殖生态研究,采用瞬时扫描法观察其求偶期日行为节律,用红外相机监测孵卵期3巢和育雏期2巢灰腹噪鹛的行为。结果表明:灰腹噪鹛4月中旬开始产卵,窝卵数2~3枚,卵长径29.6±0.4 mm,短径20.3±0.17 mm,卵重6.66±0.12 g;灰腹噪鹛75.0%的巢树为针叶树,12.5%为阔叶树,8.3%为灌木,4.2%为禾本科;灰腹噪鹛营巢成功率为86.7%,孵化成功率为60%,繁殖成功率为43.3%,影响其繁殖成功率的因素是人为干扰和天敌捕食;求偶期灰腹噪鹛觅食行为占总时间的32.03%,移动占29.27%,上午觅食、移动及鸣唱行为达到高峰,下午休憩行为偏多;孵卵期的主要行为是卧巢孵卵,占总时间的85.31%,翻卵占5.02%;育雏期亲鸟理巢行为占39.74%,卧巢占35.92%,喂食频率平均为2.95次·h-1,灰腹噪鹛单亲喂食频次多于双亲共同喂食。

Abstract: The browncheeked laughing thrush (Garrulax henrici) is endemic to China, and little work on its breeding biology has been done. From April to July of 2016, we investigated the breeding ecology of Garrulax henrici on the campus of Tibet Agriculture and Animal Husbandry College in Linzhi, Tibet. The behaviors during courtship period were observed by instantaneous scanning method, and behavioral rhythms of incubation and brooding period were monitored by infrared cameras. The results showed that 75.0% of the Garrulax henrici nests were built in conifers, 12.5% in deciduous trees, 8.3% in shrubs, and 4.2% in Poaceae plant. The clutch size was 2-3, egg length 29.6±0.4 cm, width 20.3±0.17 mm, weight 6.66±0.12 g. Nesting success rate was 86.7%, hatching success rate 60%, reproductive success rate 43.3%, and the factors impacting reproductive success were human disturbance and predation. In courtship period the foraging behavior percentage of G. henrici was 32.03% and moving was 29.27%. G. henrici had peak time for foraging, moving and singing in morning, and spent more time on resting in afternoon. The main behavior during incubation period was sitting in nest and incubation, accounting for 85.31% of total time and eggturning accounting for 5.02%. The behaviors in brooding period were mainly clearing up nest (39.74%) and sitting in nest (35.92%), and the mean feeding frequency was 2.95 times per hour. Feeding of G. henrici was mainly done by single female or male rather than by parents simultaneously.
