近年来，中溪湖野生保护区高峰时的雪雁数量曾达到十万只左右。今年因为天气较暖，在三月的第一个周末，雪雁达到了高峰，大约有八万多只。我们去时尚有六万多只，赶来赶去还是晚了一周。

美国政府有个资助计划，控制雪雁的数量，避免爆炸性地增长破坏生态环境。中溪湖保护区允许登记获准的猎手日出前和日落后的半小时内猎杀雪雁，每次限量十五只。我们曾于凌晨在湖区听到了枪声。下面这张照片拍的是猎手在布置假雪雁阵，大概是要做诱饵以吸引真雁来上钩。http://i38.photobucket.com/albums/e137/qqqny/0902/11-031409B-264a1.jpg?t=1237646291

清晨的中溪湖，宁静而又平和，远处不时传来雪雁的鸣叫。我们天不亮就赶到了观雁点，不巧碰上阴天，没能拍到日出时雪雁腾飞的景象。

三月底之前，这里的雪雁都将北飞至极地附近的繁殖栖息地。再见了，雪雁，再见了，中溪湖！
