摘 要: 对黑枕黄鹂的分布和数量、迁徙及活动规律、繁殖习性作了全面系统的报道.黑枕黄鹂分布于海拔800m以下的低山阔叶林中,在海拔300m的次生阔叶林中种群数量较大,为典型的低山带鸟类.春季迁来时间一般在5月中旬,8月中下旬迁出.主要在阔叶林中的阔叶树上营巢.巢位选择过程中,巢址多在树冠下层的外侧,巢筑在离树干较远的侧枝水平枝杈间.营巢期6~7d.窝卵数为3~5枚.雏鸟一般13.5d离巢.雏鸟生长方程为:W=59 11+e-0 613(t-1.994).The paper documented the distribution, number, migration, activities and breeding habits of Black-napped Oriole(Orilous chinensis)in detail. It distributes in the deciduous forests of low mountains where the elevations are below 800 m,the population quantity of Black-napped Oriole are high in the secondary deciduous forests where the elevations are below 300 m,it is typical bird that distributes in low mountains. They migrated in at the middle of May and migrated out at the middle to the last ten days of August. They built nests in broadleaf forests and mainly on broadleaf. The nest-sites locates on the outside of crown of a tree ,there they selected branches with two level smaller branches. The building nest stage is about 6 to 7 days. The clutch size is 3 to 5.The nestlings leave nest on the 13.5 days. The growth equation of nestlings is: W= 5911+e-0.613(t-1.994).
