In 1989, 313 foraging flights of common terns in the Wadden Sea were radio-tracked. The feeding trips lasted on average 115 min covering about 30 km per flight. Completely tracked flights had a mean radius of 6.3 km. The terns preferred distinct foraging areas in the Wadden Sea. These were visited at site-specific phases of the tidal cycle resulting in a temporal and spatial pattern of foraging, caused by the site-specific and tide-related fluctuations of food availability.
1989年，对瓦登海313次普通燕鸥觅食飞行进行了无线电追踪。觅食行程平均持续115分钟，每次飞行约30公里。完整追踪的飞行平均半径为6.3公里。燕鸥更喜欢在瓦登海特定的觅食区域。它们在潮汐周期的特定阶段访问这些区域，从而形成了觅食的时空模式，这是由食物可获得性的特定地点和与潮汐相关的波动造成的。
