Why do ducks swim in a row?
Is it really as simple as follow-the-leader being the easiest way to move a group through the reeds as suggested by Yahoo!7 Answers? Sounds good for followers but what's in it for the leader?
Movement in a column is always the fastest way to move when there are obstacles, and there are always obstacles on the ground. If the group has to swim through some reeds, or go around an angry heron, it's easiest to just follow the leader. Swimming in a spread out formation requires teamwork which most animals aren't willing to commit to.
In addition, moving behind the leader allows you to draft, reducing the amount of drag you face, but this is only relevant if you are pretty close.

A little about Mallards
The Mallard is a rare example of both Allen's Rule and Bergmann's Rule in birds. Bergmann's Rule, which states that polar forms tend to be larger than related ones from warmer climates, has numerous examples in birds. Allen's Rule says that appendages like ears tend to be smaller in polar forms to minimize heat loss, and larger in tropical and desert equivalents to facilitate heat diffusion, and that the polar taxa are stockier overall. Examples of this rule in birds are rare, as they lack external ears. However, the bill of ducks is very well supplied with blood vessels and is vulnerable to cold.

Writing From the Inside Out
A young writer, if he is unknown, can be at a party and watch what everyone is doing. If he has a marveluos ear for dialog, he can wake up the next morning and remember all that was said and how it was said. He is a bird on a branch. Sees like a bird and writes books that are extraordinarily well observed. But once he is successful, especially if that happens quickly, it's as if the bird were now an emu. It cannot fly. It grows haunches and foreshoulders and a mane: lo and behold, it is a lion. And everyone is looking at the lion, including the birds. But it is a lion with the heart of a bird and the mind of a bird. So there is a terrible period when the transmogrified emu is trying to live like a lion and has little talent for it. Then the beast begins to experiment. When it runs, it now sees other animals scamper. It takes a while - often years - for the writer to get to appreaciate his effect on others, and even longer to begin to understand human beings again. In the old days, he could write about friends, enemies, and strangers by intuition, by induction; now he puts it together by deduction. Of course, he does have more material on which to work his deductions.
