When a flock of birds fly, why do they fly in a V shape2007-11-24 17:26:16Answers:

Scientists who have studied formation flight believe that birds fly in this way for two reasons. The first reason is that the shape of the formation reduces the drag force that each bird experiences compared to if it were flying alone. This decrease in drag occurs thanks to the formation of wingtip vortices described in previous articles

These vortices are generally undesirable because they create a downwash that increases the induced drag on a wing in flight. However, this downwash is also accompanied by an upwash that can be beneficial to a second wing flying behind and slightly above the fir

Scientists have given a clear demonstration of why birds fly in a "V" formation.

It is something the animals do because it reduces energy expenditure, helping large birds to migrate in groups.

Everything that has been done until now has been theoretical, based on aerodynamic models

A French team was given a unique opportunity to study great white pelicans that had been trained to fly behind an aircraft for a feature film.

They found that the birds' heart rate went down when they were flying together and they were able to glide more often.

The energy saving may be crucial for migrating birds, which spend thousands of kilometres on the wing.

So that every bird can see the 'Alpha' bird and follow them

it has to do with "drafting." the first bird breaks the wind so the ones behind it dont have as much wind resistance

---

It's to do with the wind and how they can effortlessly keep flying.

This is mainly to do with geese and the like when they are migrating. The bird at the front creates a sort of wind wave and the other birds behind fly in its drag. That way the birds behind use less energy. The lead bird is frequently relieved by others in the flock and they all take a turn at the 'blunt end.'
