why do flock of birds fly in a v shape?

Answer 1

they only have one map, and johnny at the front has it...

its aerodynamics.

Answer 2

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. Another theory as to why birds fly in formation is that this orientation allows the birds to communicate more easily. The V formation provides the birds with good visual contact of each other to keep the flock together. This communication minimizes the possibility of losing birds along the way as the formation crosses vast distances during migration.

Answer 3

Birds use a v shape to conserve energy. They take turns in the "point" of the "v". They draft off eachother, much like racecars do! They have a rotation, so during the course of a long flight, most of the birds (excluding the very young) have a turn as the lead bird. That way, they aren't all completely worn out after a long flight!

Answer 4

Well, first off the majority of birds do not fly in any kind of formation when migrating. Look at those huge flocks of blackbirds and robins. Just a random flock.

Usually it is larger birds that fly at high altitudes, above 1000 feet. Like Canada geese or sand-hill cranes or surf scooters.

Answer 5

The reason is that the shape of the formation reduces the drag force that each bird experiences compared to if it were flying alone.

Answer 6

i think there is less air resistance this way, the birds take it in turns to be at the front because this is the most tiring place to be on long flights. it makes the flock more aerodynamic.

Answer 7

They all Follow the lead bird and use the airflow from one to another that way they get a rest when they drop back into the V
Very effective for what they say have no brains!

Answer 8

Geese fly in V shape, to cut on energy they expel.

Answer 9

More efficient for long flights.

Answer 10

when they are mygrating to another country fastest is at the front
