一只鸟连接两端湿地
国家林草局8月17日报道,斑尾塍鹬可在新西兰、澳大利亚与北半球繁殖地之间完成超长距离迁徙,鸭绿江口是其中重要的停歇补给地。报道记载,今年春季当地监测到33只带不同地区彩色旗标的鸻鹬,最多一次记录6万只斑尾塍鹬集结。
这些数字来自保护区监测,不能被理解为游客的保证清单。真正适合观赏大群迁徙的窗口主要在春季4—5月,具体日期受潮汐和迁徙进程影响。
识别与旗标记录
斑尾塍鹬体型较大,嘴长且轻微上翘,腿较长。繁殖羽雄鸟腹部偏红褐,非繁殖羽整体更灰。飞行时尾部横斑和较浅色腰背有助识别,但远距离需同时比较体型、嘴形和群体行为。
发现腿上彩旗标时不要靠近或围堵。用长焦或单筒望远镜记录旗标颜色、上下位置、字母数字、左右腿、日期和大致湿地区域;只有信息清晰时再提交给正规环志或保护机构,不能猜测缺失字符。
把鸟浪留给鸟
天文大潮可能把鸟群推到有限的高潮栖息地。观鸟者应停在官方观察位置,避免站在鸟群与安全高地之间,不沿堤岸追赶飞行方向,也不使用无人机获取俯拍画面。
不公开保护区内部点位或实时高潮栖息地。团队采用小人数、低声交流和轮流使用单筒镜的方式,让迁徙鸟能够持续休息和进食。
One bird links wetlands at opposite ends of the flyway
The August 17 NFGA feature describes Bar-tailed Godwits travelling between New Zealand or Australia and northern breeding grounds, with the Yalu Estuary serving as a crucial refuelling stop. This spring, monitors recorded 33 colour-flagged shorebirds from several regions; one count reached 60,000 Bar-tailed Godwits.
Those are protected-area monitoring figures, not a guaranteed visitor list. The main spectacle is usually in April and May, with exact timing controlled by tide and migration progress.
Identification and colour-flag notes
Bar-tailed Godwit is a large wader with long legs and a long, slightly upturned bill. Breeding males are rufous below; non-breeding birds are much greyer. A barred tail and paler rump-back pattern help in flight, but distant identification should combine size, bill shape and flock behaviour.
Never approach or surround a flagged bird. From distance, note flag colour, upper/lower position, letters or numbers, left or right leg, date and broad wetland area. Submit only clear records to an official ringing or conservation programme; never guess an unread character.
Leave the bird wave to the birds
A spring tide can compress flocks onto scarce high-tide roosts. Remain at official viewpoints, do not stand between birds and safe high ground, and never chase their line of flight or launch a drone for an overhead image.
Do not publish internal reserve points or live high-tide roost locations. Keep groups small, voices low and share the scope so migrants can continue resting and feeding.
