| 摘 要： | 肯尼亚纳瓦沙(Naivasha)和内库路(Nakuru)湖区有2种共生画眉鸟,即黑智画眉(Turdoides sharpie)和箭纹画眉(T. jardeneii)。本文研究旨在评价肯尼亚纳瓦沙湖区2种鸟的生境分割机制。沿纳瓦沙和欧罗依登(Oloiden)湖岸线,每种鸟取7组样本,对其所属的生境特点进行研究。2种鸟所属的生境显著不同,箭纹画眉仅属于岸线上地被丰盛的密林中,而黑智画眉则属于地被低矮的丛状疏林中。文章同时也讨论了2种鸟的摄食习惯和社会行为。图2表4参18。

| Abstract: | Two species of babblers, Black-lored Babbler (Turdoides sharpie) and Arrow-marked Babbler (Turdoides jardeneii) are sympatric around lakes Naivasha and Nakuru, Kenya. This study was carried out to assess the habitat partitioning mechanisms of the two species around Lake Naivasha area. The charactretistics of habitats used by seven groups of each species were studied along the shorelines of lakes Naivasha and Oloiden. The two species differed significantly in the habitat characteristics. Arrow-marked Babbler is restricted to shorelines with dense tree and ground vegetation cover while Black-lored Babbler occupies open areas with sparsely distributed small trees and short ground vegetation cover. Observations on the feeding habits and social behaviours of the two species are also discussed. |
