四川老君山自然保护区红嘴相思鸟繁殖生态初报

The Preliminary Study on Breeding Habit of Leiothrix lutea at Laojunshan Nature Reserve,Sichuan

2011年7～8月在宜宾市屏山县老君山自然保护区对红嘴相思鸟Leiothrix lutea的繁殖生态进行了初步研究。研究结果显示,红嘴相思鸟巢主要营造于方竹Chimonobambusa quadrangularis(Fenzi)Makino、柃木属Eurya树枝和藤蔓上,藤蔓有悬钩子属Rubus、猕猴桃Actinidia chinensis、木通属Akebia等。巢址环境温度(22.01±0.35)℃,湿度(88.30±0.81)%;巢材主要有树叶、树皮、细藤、细树根、细树枝、方竹叶、草叶、细草茎、苔藓、人造纤维、棉类、塑料、过滤嘴纤维等;巢外径(85.31±1.09)mm×(94.00±1.37)mm、内径(55.77±0.69)mm×(62.48±0.70)mm、巢深(54.78±1.14)mm、巢高(80.43±2.39)mm;窝卵数3.125枚/窝,孵化期12d,孵化工作主要由雌鸟担任;巢内育雏期10～12d,雌雄共同育雏,雄鸟占主要。繁殖成功率75.00%。

Breeding habit of Leiothrix lutea was preliminarily studied at Laojunsban Nature Reserve of Yibin, Sichuan province, from July to August, 2011. The results showed that the nests were mainly built in Chimonobambusa quadrangu- laris （Fenzi） Makino, plants of Eurya, Rubus, Actinidia chinensis and Akebia. Ambient temperature of the nest-site was （22.01 ± 0.35 ） ℃, the relatively humidity was 88.30% -± O. 81%. The building materials mainly include slimsy branches, leaves, cortices and roots of several plants, muscus, plastics and so on. The average depth of nests is （54.78 ± 1.14） mm, with inner diameter of （ 55.77 ± 0.69 ） mmx （62.48 ±0.70） mm and outer diameter of （ 85.31 ± 1.09 ） mm x （94.00 ± 1.37） mm. The mean clutch size is 3. 125. Incubation required 12 days before the nestlings were born. Females played a major role in the incubation. Fledglings were bred for 10 - 12 days and the male is in charge of breeding. The breeding suc- cess rate was 75.00%.
