中新社河北衡水11月19日电 (裴国荣 崔志平 张凯)“京津冀最美湿地”衡水湖数万只候鸟齐飞形成“鸟浪”奇观，“观鸟游”热度近期持续升温。
“这几天正是候鸟迁徙高峰，每天清晨和傍晚，这样的‘鸟浪’奇观都会准时出现。”19日，河北衡水滨湖新区资源保护局副局长张余广手持望远镜，正在记录候鸟种类。
衡水湖位于河北省衡水市，是华北平原保持沼泽、水域、滩涂、草甸和林地等完整湿地生态系统的国家级自然保护区，也是东亚—澳大利西亚候鸟迁徙线上的重要驿站，扮演着至关重要的“中转站”与“能量加油站”角色。
据张余广介绍，“鸟浪”奇观是候鸟迁徙时为共同抵御天敌，降低被捕食的风险，或提高觅食效率，大量聚集在一起形成的壮观群体飞行现象。“‘鸟浪’奇观多出现在清晨和傍晚，是因为这两个时间段与鸟类核心生存需求高度契合。”
近年来，衡水湖通过生态补水、湖岸修复等举措，水生生物资源日益丰富，为候鸟迁徙提供了充足的“能量补给”，而“观鸟游”也成为当地生态旅游的一张“名片”。
每到候鸟迁徙季，来自北京、天津等地的摄影爱好者会集中来到这里，拍摄各种候鸟在湖面上翔集的“名场面”。“刚拍到一群白鹭掠过芦苇荡的画面，太美了。”来自天津的摄影爱好者贾明明难掩激动心情。
据介绍，衡水湖观测记录到的鸟类达336种，目前已有百余种候鸟陆续飞抵此处。今年10月份以来，衡水湖景区接待观鸟游客超3万人次。(完)
