【摘要】 本文报道崇明东滩鸻形目鸟类46种,隶属5科18属。每逢迁徙季节,这些鸟类都在这里过境中转。并对其中的20种鸟类进行剖胃食性分析,结果表明:鸻鹬类以摄取底栖动物为主,其次为植物物质和砂砾等。同时还发现鸻鹬类的活动和摄食食物都限于海三棱蕉草带。因此,保护东滩海三棱鸸草带是维护鸻鹜类资源的主要因素。更多还原

【Abstract】 from 1986 to 1994, 46 species of shorebirds were observed on the Eastern Beach of Chongming Island. They belong to 5 families, 18 genus and most of them are migrants. By dissecting 197 bird stmachs of 20 species of shorebirds, we found that the animal materials occupied 64.57%, of which were mainly gastropoda, iamellibranchia and Crustacea etc., and the plant materials occupied 14.90%, of which were mainly nuts of the sea-bulrush (Seirpus x mari-queter), and the other materials were gravel and mud. Besids, we found the place where the shorebirds fed most frequetly was the sea-bulrush zone. Thus, the sea-bulrush zone on the Eastern Beach of Chongming is the most important factor to maintain the resource of shorebirds.更多还原
