曲阜河滨两种鸻形目鸟类觅食行为对人为干扰的响应

以曲阜的南沙河(沂河曲阜段)和北沙河(泗河曲阜段)两地作为对青脚鹬(C.temminck)和金斑鸻(P.dominica)2种鸻形目鸟类的观察研究基地,采用目标动物取样法和人为干扰实验法对2种鸟类进行初步研究。结果表明,青脚鹬和金斑鸻主要在河岸浅水和滩涂中觅食,金斑鸻更喜沙质基底。其食物主要为小鱼、小虾、蚯蚓、蝌蚪以及水生昆虫等动物性食物。2种鸻形目鸟类的取食频率和惊飞距离等参数在无人干扰和不同的干扰级别下都存在着显著差异,而且滨鸟觅食区的人为活动已经严重影响到以上2种鸟的觅食行为。

The Effect of Human Disturbance on Foraging Behaviors of Two Kinds of Charadriiformes in Qufu Streamside

This research aimed to study the foraging characteristics of C.temminck and P.dominic by the methods of focal-animal sampling and human-disturbance experiment at the beach of Nansha River(the Qufu section of Yihe River) and Beisha river(the Qufu section of Sihe River) in the city of Qufu from March to June,2006.Results of focal-animal sampling showed that the beach of the river and the mudflat was the main foraging areas of C.temminck and P.dominic,and the P.dominic prefers to foraging in the area with sand fundus.Fish,shrimp,earthworm and the aquatic insects were their main food.There are significant differences between the forging times and flush distances of two kinds of birds with different degrees of human disturbance.And the foraging behaviors of C.temminck and P.dominic were significantly affected by the human activities in the shorebirds foraging areas.
