Why do ducks and some other birds fly in patterns?
V-shape formations are more aerodynamically efficient for the group. The air directly behind a wing is pushed downwards (called downwash), and the air behind and to the side of a wing is pushed upwards (upwash). This is due to the vorticies formed on the wing tips.
The Short Answer
V-shape formations are more aerodynamically efficient for the group. The air directly behind a wing is pushed downwards (called downwash), and the air behind and to the side of a wing is pushed upwards (upwash). This is due to the vorticies formed on the wing tips. Flying in the downwash is harder, and flying in the upwash is easier, which is why ducks, geese, and aircraft flying in formation position themselves behind and to the side of the leading bird. [This diagram](_URL_0_) shows this nicely.
