Why birds fly in a V formation

Why do many birds fly in a V formation? The wonderful video curators at The Kid Should See This came across this excellent 2014 clip above from the science journal Nature explaining research into the aerodynamic advantages of the formation. From Nature:

The ibises position themselves within the V so that they benefit from the flow of air created by the bird in front. They carefully time their wing flaps with their flock mates', to get an extra lift when flying high.
