如果不懂的话，你一定以为它在玩水跺脚脚。

其实不是，这只海鸥实际上是在捉虫子找吃的。

通过不停地踩水，模仿雨滴落在地面上的声音，来吸引蠕虫

至地面，然后吃掉。

许多种类的蠕虫能够通过感觉到振动来感知环境中的雨水。当雨水落到地面上时，产生的振动会被蠕虫感知，它们会将这种振动解释为是安全的、湿润的环境条件，从而更有可能出现在地面表层以寻找食物或为了交配。这是一种生存机制，因为雨后的地面更容易挖掘，同时湿润的条件对它们的生存也更为有利。

海鸥通过拍打地面来模仿这种由雨点落下产生的振动效果。它们可能会使用脚或是嘴来敲击地面，从而产生类似于雨滴击打地面的声音和振动。这种行为诱使蠕虫向地面表层移动，从而使海鸥能够轻易地捕食到它们。

这种觅食策略是海鸥对其大自然的理解和适应的一个例证，通过发展出复杂的行为来利用其生态系统中的资源。所以，这也算证明海鸥是聪明的了。

也有真的在跺脚不为蠕虫的，或许只是期待另一根薯条罢了。

当然，还有其他例子。

比如零元购海鸥：

各种零元购：

这是一只在英国德文郡

的Tesco Extra超市里频繁偷窃零食的海鸥，据不完全统计，这只海鸥偷窃了价值约300英镑、总重17公斤的食物。工作人员都懒得阻止了，毕竟是一天快乐的源泉，还给它起了个名字Steven。

不管是零元购海鸥还是海滩强盗，这些都是海鸥适应人类社会的体现，聪明的象征。

2023年，科学家在英国布莱顿海滩

进行了一个实验：他们摆放了两种不同颜色的食物包装袋，并有一个人类在旁边吃着与其中一种包装袋颜色相同的食物。结果显示，银鸥

更倾向于（95%）选择与人类正在吃的食物颜色相同的那包。简言之，还是人类嘴里吃的香。

[1]

这项发现表明，银鸥不仅仅是机会主义者，它们实际上在学习和利用人类的行为来做出更好的觅食决策。
