why do geese fly in a v2007-11-24 17:27:02Answers:

the one in front has the map (sorry)

If you look closely enough you will see that they are actually all on leads and the one at the front is their owner!

---

Most migrating birds do as its more aerodynamic and they all follow a leader - but they fly slightly on the wing of the bird in front so that they can see where they are going..hence the V shape..

---

They take turns being at the tip of the V - and the lead goose will peel off after some time and be replaced by another.

It is the best formation to fly in where the geese will meet with the least amount of wind resistance.tha's why the lead goose will retire after some time of absorbing the most force

---

more aerodynamic and the strongest one leads, when he tires another one takes his place!

---

i have often wondered this, i think its to ward off predators, makes them look bigger in a v.

---

aerodynamics, the goose at the front "breaks" the air Resistance making the ones behind life easier. If you watch for long enough you will see that the one at the front is constantly changing.The v is the best way of reducing the outside edge resistance. effectively this is an energy conservation system allowing geese to fly further for longer. In endurance cycling eg tour de France you can see a little of this going on the lead cyclist is often constantly changing until near the end of the race

Cos they are insecure

It reduces the wind resistance on all the birds except the one up front, thats why they swap.
