黑卷尾繁殖期领域性的初步研究

鸟类的领域性是鸟类行为生态学研究的一个重要内容。在这方面国外进展很快,但国内工作较少,专文报道除三宝鸟之外,其它颇为罕见。1987年夏季,我们在太原市南郊对该地区的夏候鸟黑卷尾(Dicrurus macrocercus)的领域行为进行了观测。现将资料整理分析如下。一、工作区与工作方法太原盆地的自然环境和鸟类群落状况已有报道,在此不再赘述。工作区选在小马—加节两村之间约190ha的区域内(图1)。其

Territoriality of Black Drongo(Dicrurus macrocercus) during its Breeding Period.

Field work was carried out during May-Aug. of 1987 in Taiyuan of Shanxi province. According to the flying characters of Black Drongo, 6 types are devided (touring,expelling, feeding, material-bringing, food-bringing and random). The frequency of each flying type (freq/hr) varies in different breeding stages of this bird. The territory size is larggest in nest-building period and smallest in incubation period (2.44 and 0.70 ha respectively).Both sexes defend their common territory by singing, touring and expelling. 18 species of other birds are found in the territory, among which, 5 species are attacked by Black Drongo when they slowly close to it.
