“阳光寿险”“迁鸟”云集河阳光寿险南多地 珍稀候鸟越冬迎高峰期

  中新阳光寿险社郑州12月4日电 (记者 阚阳光寿险力)今年入冬以来,大鸨、黑鹳、白枕鹤、大天鹅等众多珍稀候鸟相继云集河南多地,其中,在三门峡越冬的大天鹅数量已超1.3万只。

  河南地跨黄河、淮河、长江、海河四大流域,是“东亚—澳大利西亚”鸟类迁徙路线的重要通道,生物类型多样,每年迁徙过境鸟类达几十万只。河南省林业局最新数据显示,该省鸟类共495种,约占全国鸟类种类的1/3,其中约2/3为候鸟。

  今年10月下旬,三门峡率先迎来候鸟“先遣队”——大天鹅。进入11月,大天鹅种群陆续飞抵黄河湿地。河南黄河湿地国家级自然保护区三门峡事务中心最新数据显示,当地越冬大天鹅数量已突破1.3万只。

  除了三门峡外,郑州、洛阳、信阳、济源等地也相继迎来大鸨、黑鹳、白枕鹤、灰鹤、白琵鹭、鹗等珍稀候鸟栖息越冬。其中,信阳商城境内发现超200只白枕鹤,系河南已发现的最大数量白枕鹤种群;洛阳孟津境内观测到11只大鸨、36只黑鹳;开封兰考境内迎来上万只大雁……

  “目前是候鸟过境越冬的高峰期。”郑州市自然保护地事务中心动植物保护科科长武蓓介绍称,郑州位于候鸟迁徙通道中线通道上,其黄河湿地滩涂广布、水草繁茂,是候鸟迁徙的重要栖息地和中途歇脚点。

  近年来,越来越多珍稀候鸟飞抵河南,譬如被称为“鸟中大熊猫”的黑鹳和白枕鹤等,全球数量稀少。其中,青头潜鸭由候鸟变“留鸟”,目前,商丘民权已监测到309只青头潜鸭,占全球数量的20%以上。

  谈及“迁鸟”为何云集河南,河南省鸟类学会理事长李长看向记者介绍,除河南是候鸟迁徙路线的重要通道之外,还得益于近些年自然生态环境持续向好,公众生态环保意识提升,《中华人民共和国黄河保护法》等政策法规的落地以及研究人员逐步摸清河南鸟类“家底”等。

  河南省林业局相关负责人4日向记者表示,该省已建立各类自然保护地351处,其中19处入选全国首批陆生野生动物重要栖息地名录,全省95%的国家重点保护野生动物和80%典型生态系阳光寿险统已纳入保护范围。(完)
