摘要
黑嘴鸥仅在我国沿海地区繁殖，迄今共发现４个繁殖地点，河北省秦皇岛市滦河口是其中之一。１９９５～１９９７年的野外调查结果表明，滦河口黑嘴鸥繁殖群体目前呈下降趋势，原因是黑嘴鸥繁殖地湿地的生境改变及人为因素影响。
Luanhe Estuary, located at the Bohai Sea coast near Beidaihe, is one of the four so far known breeding sites of the Saunder′s Gull (Larus saundersi). Results of the field work in 1995～1997 on the breeding colony of the gull revealed the fact that a dramatic declining happened to the breeding pairs of the gull colony due to the habitat degradation and loss as well as the human disturbance, and hence a prompt action for conservation is needed urgently.
