【摘要】 2021年3月5日,在甘肃省嘉峪关草湖国家湿地公园(39°54’49.20″N,98°26’39.32″E)记录到配对进入领域行为期的欧鸽(Columba oenas),确认其为甘肃鸟类分布新纪录。通过样方调查和行为取样探明该鸟的巢址特征和警戒行为,经查阅相关文献资料及查询中国鸟类记录中心数据,对该鸟目前的地理分布进行了归纳总结,初步认为该鸟在甘肃省的出现与其分布区的持续东扩有关。欧鸽当前在甘肃省分布的种群数量不多,且不连续,初步推测欧鸽可能已在本省繁殖,为罕见留鸟。更多还原

【Abstract】 On March 5,2021,we found a flock of Columba oenas which began to pair for breeding and have showed territorial behavior at Caohu National Wetland Park( 39°54’49. 20″N,98°26’39. 32″E) in Jiayuguan city of Gansu Province. This was identified as a new distribution record of C. oenas in Gansu Province. The quadrat sampling and behavior sampling methods were adopted to analyze the characteristics of nest site and the vigilance behavior of C. oenas,and then we consulted the related literature and accessed the database of China Bird Report Center and summarized the current geographical distribution of the species. We preliminarily confirmed that the presence of C. oenas in Gansu is mainly due to the fact that its distribution range continued to spread to the east. The population of C. oenas in Gansu was small and their distribution was also discontinuous. We preliminarily speculated that this species could breedin Gansu Province,so that it could be regarded as a rare residental species.更多还原
