Many people love to watch dogs because of their seemingly funny behavior. Some people even love ducks so much that they have them as pets. One of the most endearing duck behaviors is the wagging of their tails. Many people find it amusing when they see ducks walking around and wagging their tails. Aside from being amused though, there are also people who wonder why some ducks seem to wag their tails a lot. When the animal behavior experts are asked, many would point the tail-wagging as some kind of mating behavior. This is especially true for some duck species wherein the males do the tail wagging while in water. In Mallard ducks for example, the males are known to do some neck shaking and tail wagging while trying to get close to a female duck. Aside from wagging their tails, male Mallard ducks are also known to raise the tips of their wings during the so-called courtship dance.

以鸭子在地上摇尾巴为例，有些人认为它们这样做是出于高兴和兴奋。当鸭子从桶里喝水或刚吃过食物时，这一点尤其明显。许多人看到许多鸭子在这种情况下胡言乱语。食物和水是许多鸭子的能量和快乐的来源，摇尾巴可能仅仅意味着它们对食物很满意。

例如，对于刚从水里出来的鸭子来说，摇尾巴确实是摆脱羽毛中水分的必要手段。摇摆可以帮助他们更快地干燥，并允许他们做其他活动。对一些人来说，鸭子摇尾巴只是大自然的一种影响，因为鸭子走路时尾巴会左右摆动。这种自然的运动总是让人觉得鸭子经常摇尾巴。
