There are a lot of unanswered questions in the world, one of which is why geese and other migrating birds fly in a 'v' formation. And come to think of it, I've never even questioned why they do until right now. Good thing I did some research to share with everyone!

It actually turns out that migrating birds fly in a 'v' formation to preserve their energy, which allows them to fly longer distances without stopping to rest. The bird in the front utilizes the most energy, but then rotates to the back of the pack which allows it to rest a little bit.

When the birds rotate back they also fly slightly above the bird in front of them so as to reduce wind resistance. Who knew, right?

And the 'v' formation isn't just useful when flying, but if you've ever seen 'The Mighty Ducks' you already know that.
