摘    要:2008年和2009年的4~8月,在四川省雅江县帕姆岭对棕背黑头鸫Turdus kessleri的繁殖生态进行了初步观察.该鸟繁殖期在4月下旬至7月上旬,营树上巢,营巢树种为高山栎Quercus aquifolioides和鳞皮冷杉Abies squamata.窝卵数为2~3枚(n=7),平均卵重(7.96±0.03)g(n=8),卵长径(32.7±0.17)mm,短径(21.9±0.13)mm(n=13),雌雄共同孵卵,以雌性为主,孵化期为15~17 d(n=2),孵化率为83.3%(n=18).雌雄共同育雏,以雄性为主,雏鸟出飞后主要在巢周围的林下或灌从活动,这时亲鸟仍会对幼鸟喂食.在同一繁殖季对巢有重复利用的现象.

关 键 词:棕背黑头鸫  繁殖    育雏行为

Abstract:From April to August in 2008 and 2009,the breeding habits of Kessler’s thrush Turdus kessleri were studied at Pamuling mountain in Yajiang county,Sichuan province.The results showed that the breeding period of T.kessleri was from latter half of April to first half of July.T.kessleri nested mainly in oak bush,and also in fir forest.The average clutch size was 2.6±0.24(2~3,n=7),the mean egg weight was(7.96±0.03) g(n=8),and the mean egg size was 32.7 mm×21.9 mm(n=13).Both male and female undertake hatching,but mainly by female,the hatching success rate of 7 nests was 83.3%(n=18) and nestlings hatched in 15~17 days(n=2).The male and female fed the nestling together during both the brooding period and post brooding period,but mainly by male.The nestling flew out of the nest moved around the nest area,during which parents keep fedding nestlings.Nest re-usage phenomenon is observed in one breeding season.
Keywords:Turdus kessleri  breeding  nest  brooding behavior
