The temporary reduction of clutch size, egg size and breeding success of the Common Tern during the breeding period of 1983 at the Lower Saxonian Wadden Sea (West Germany) was correlated with heavy rainfalls on the days preceding egg-laying (Figs. 2-4). Possible effective mechanisms and the result that the reduction of clutch size was not observed for colonies at the mainland coast are being discussed (Fig. 4).
1983年繁殖期，在德国下萨克森州瓦登海，普通燕鸥的窝卵数、卵大小和繁殖成功率的暂时降低与产卵前几天的暴雨有关（图2 - 4）。文中讨论了可能的有效机制以及在内陆海岸的鸟群未观察到窝卵数减少的结果（图4）。
