摘　　要：海南(Gorsachiusmagnificus)是世界上最为濒危的鸟类之一。在上思县海南的活动区,分布有水鸟32种;其中在海南主要觅食地浅水区活动的有14种,包括11种白昼活动的水鸟和3种夜行性水鸟,海南属夜行性水鸟。由于生境使用时间不同,海南与大部分白昼活动的水鸟形成生态分隔;夜鹭在觅食生境的使用和活动时间上,与海南重叠最多,有可能对海南产生重要的生态影响,值得进一步深入研究。研究还表明,冬季和初春是调查海南的分布和数量的重要季节。Gorsachius magnificus is the most endangered bird species. There are 32 waterbird species living in the distribution area of Gorsachius magnificus in Shangsi county,of which 14 waterbird species feed in the shallow water area,including 11 diurnal waterbird species and 3 noctural waterbird species.Gorsachius magnificus is nocturnal waterbird species and is ecological isolation from most dicurnal waterbird species as their usage of habitat is different. The feeding sites usage and activity time of Nycticorax nycticorax and those of Gorsachius magnificus overlap,it may result in important ecological influence on Gorsachius magnificus and is worth further studying. The study indicate that winter and the beginning of spring are the important sensons for the survey of the distribution and quantity of Gorsachius magnificus.
