why birds fly in v pattern?

Anyone watching the autumn sky knows that migrating birds fly in a V formation, but scientists have long debated why. A new study of ibises finds that these big-winged birds carefully position their wingtips and sync their flapping, presumably to catch the preceding bird's updraft—and save energy during flight.

When migrating, however, birds often do climb to relatively great heights, possibly to avoid dehydration in the warmer air near the ground. ... Birds can fly at altitudes that would be impossible for bats, since bird lungs can extract a larger fraction of oxygen from the air than can mammal lungs.

Why do the birds fly?(Tales of Berseria) Bird bodies are made to fly. They have light bones, strong legs, and specially shaped wings. Flying helps birds get away from animals that want to eat them, and makes them better hunters, too.

It is also used by some species to display during the breeding season and to reach safe isolated places for nesting. Flight is more energetically expensive in larger birds, and many of the largest species fly by soaring and gliding (without flapping their wings) as much as possible.

Like many other birds, homing pigeons can use the position and angle of the Sun to determine the proper direction for flight. The map mechanism, however, remains a bit of a mystery. Some researchers believe homing pigeons use magnetoreception, which involves relying on Earth's magnetic fields for guidance.

Bird's wings have feathers and strong muscles attached to them. With the help of their strong arm and chest muscles, birds flap their wings and fly. The bodies of birds are very light which help them to fly easily. This is because the bones of birds are thin, light and hollow.

When it comes to powered animal flight, bats have always seemed to come second to birds. But scientists who flew a plane to track the flight of Brazilian free-tailed bats have clocked these winged mammals flying at speeds rivaling those of the fastest birds.

The greater freedom of wing movement in birds allows them to fly without a vertical stabilizer. ... The short and simple answer is that birds change their entire wing and tail shape. This is different from airplanes that have a fixed wing structure with small surfaces that move.

The classic research on how flocking birds move in unison comes from zoologist Wayne Potts, who published in the journal Nature in 1984. His work showed that bird in flocks don't just follow a leader, or their neighbors. Instead, they anticipate sudden changes in the flock's direction of motion.

It is for reducing the air drag/resistance that would be imparted on the birds had they been flying in a straight line. Often their migration journey is very long spanning months and continents and hence it is important that they reach their destination safely.

Eventually, the fledglings — young birds learning to fly — come to realize that falling from the nest is a bit easier if they spread their wings, according to Boston University. Once they learn to spread their wings, flapping them is the next step, and soon that flapping becomes flight.

Scientists in America have made a special wind tunnel to make it easier to study the way that tiny birds fly in windy weather. ... The wind tunnel makes strong gusts in a small space, so the birds can fly against it without actually going anywhere. The scientists film them in super slow-motion to watch how they move.

Sharing a common goal: As each goose flaps its wings it creates “uplift”, an aerodynamics orientation that reduces air friction, for the birds that follow. By flying in a V-formation, the whole flock achieves a 70% greater flying range than if each bird flew alone.

These birds are symbols of love, prosperity, harmony and peace. Seeing a dove flying in front of you is a symbol of good luck and love that is coming your way. Especially white dove is considered to be a pleasurable sign to see. White doves are symbols of love and relationships, so they are always welcomed.

Why do the birds fly?(Tales of Berseria) ... Flying helps birds get away from animals that want to eat them, and makes them better hunters, too. Flying also helps them travel from cold places to warm places, called migration (my-GRAY-shun). It's in their nature, their instinct.
