中新网广州9月22日电 (程景伟 林荫)据广东省林业局22日消息,广东湛江爱鸟协会成员9月18日在湛江廉江一处荷塘湿地观测并拍摄到6只国家一级保护野生动物彩鹮,创下湛江单次观测彩鹮数量最高纪录。
彩鹮是中等体型涉禽,体长50厘米至70厘米。其羽毛在阳光下能变幻出深栗色、翠绿色、青铜色和紫罗兰色等多重金属光泽,由此得名并收获“五彩斑斓的黑”的趣味别称。该物种曾在国内一度绝迹近70年,直至2003年后才在全国各地陆续重新被发现。
“我一到那里就看见它们了,但没想到能有6只,实在是太高兴了!”据湛江爱鸟协会理事王大勇介绍,廉江这片荷塘湿地植被丰茂、水质优良、人为干扰少,是湛江境内鸟类资源富集的重要栖息地。今年二三月,该区域已有彩鹮活动的踪迹。此次他和朋友发现6只彩鹮在此集群栖息、觅食活动,种群数量远超以往观测记录,实属罕见。
当日现场人员较少、环境静谧,王大勇一行得以在二三十米安全距离内清晰记录彩鹮的活动状态。当时,6只彩鹮或在浅滩水域自由觅食、栖息,或振翅飞翔,适应度良好。9月19日,已有不少观鸟爱好者闻讯前往现场观测记录。业内人士表示,彩鹮迁徙特性较强,停留时间并不固定,但若持续维护好栖息地环境、减少人为惊扰,它们或将在此长期活动。
据本地鸟类观测资料记载,此前彩鹮在湛江多为零星出现。此次一次性发现6只个体,实现了湛江彩鹮观测数量的历史性突破,直观反映出区域生态环境持续改善。
近年来,湛江持续推进湿地生态修复、野生动物保护等工作,不断完善湿地管护体系,严厉打击破坏野生动物栖息地、惊扰野生鸟类等违规行为,持续优化生态格局,为各类珍稀水鸟、迁徙鸟类营造优质的栖息繁衍环境。
进入9月,广东再一次迎来秋季候鸟迁徙关键期,大批候鸟陆续南下停歇、补给、越冬。近期,一只脚带环志“L5”的国家一级保护野生动物勺嘴鹬现身阳江市阳西县,白眉鸭、黑尾塍鹬、红脚鹬等候鸟也陆续飞抵深圳福田……作为东亚-澳大利西亚候鸟迁徙通道核心省份,广东历史记录有野生鸟类584种,其中具有迁徙属性的鸟类412种。
据广东省林业局介绍,广东将持续织密全域鸟类保护防护网,压实生态保护责任,常态化开展巡查管护,严厉打击跨区域盗猎、贩运野生鸟类违法犯罪;同时,倡导市民及生态爱好者自觉文明观鸟、静音拍摄、保持安全观测距离,共同守护野生鸟类栖息地。
