why do birds fly in a v with one side longer?

What is the reason geese flying formations have one side longer? Because they seldom fly directly into the wind. The angle of attack into the wind would make the downwind part of the formation easier to fly in terms of output. So the downwind side of the formation would be longer.

A larger group of birds boasts a much better chance of spotting a predator, or other potential threat, than a single bird has. A group of birds may also be able to confuse or overwhelm a predator through 'mobbing' (when birds attack or chase a would-be predator, to drive it away) or agile flight.

They will commonly fly in V-formation, but unlike geese, they regularly stop to hover in mid-air before reassembling and flying on (this looks quite funny). At great distances, this can be useful for telling them apart from geese.

Hummingbirds are the only birds that can fly backwards and upside down. ... Hummingbirds have a unique ball and socket joint at the shoulder that allows the bird to rotate its wings 180 degrees in all directions.

So the shape of the wing and the ability to move it through the air are the two things needed for bird and plane flight. Birds use their strong breast muscles to flap their wings and give them the thrust to move through the air and fly. In a way, birds use a swimming motion to get the lift needed to fly.

A bird has wings which helps it to fly. 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.

Birds generate lift through the motion of their wings (they are also fairly light for their volume, which helps a lot). Fish (most of them, anyhow) have a gas bladder that controls their buoyancy.

Why Flamingos Stand on One Leg. Flamingos at rest, standing on one leg. This posture may be used by the birds to conserve body heat. The brilliant pink feathers, gangly neck and upside-down eating are enough to make flamingos a spectacle at any zoo and generate a barrage of questions from curious children.

This is regardless of whether the longer side is the vertical side or the horizontal side. However, many have observed that the length is usually the vertical, and the width is the one in line with the horizontal plane.

Nights are cooler, which allows them to fly without getting overheated. Nights are also less turbulent. Geese are not soaring birds so they don't need thermals to glide on. In fact the thermals upset their normal migration because they have to struggle to remain at a constant altitude.

Wood Stork Wood Storks fly their long legs trailing behind them, unlike the short-legged pelican. The black trailing edge of the wing comes all the way to the body in Wood Storks, whereas American White Pelicans have a white gap on the wing (the tertials) before the black trailing edge begins.

There are several benefits to flying as a flock. It improves a bird's chance of survival against predators because a large group of birds is stronger and better protected and with many eyes the flock is far more likely to spot a would-be marauder. ... This enables the flock to use less energy and reduces fatigue.

IN NEED OF HELP said: In still air, a bird can fly at a speed of 10 m s–1. ... So they want the destination to be north of the bird's current location meaning that the resultant velocity must be vertically upwards.

First, it conserves their energy. Each bird flies slightly above the bird in front of him, resulting in a reduction of wind resistance. The birds take turns being in the front, falling back when they get tired. In this way, the geese can fly for a long time before they must stop for rest.

birds like ibises fly in a V formation by drafting off each other, the seventh paragraph begins by stating, “scientists do not know how the birds find that aerodynamic sweet spot.” In context, the phrase “aerodynamic sweet spot” characterizes the particular spatial relationship among birds in the formation that affords ...

In a new study, published in the journal Ibis, he suggested the reason the birds are susceptible is because they have evolved to look for movement either side and potential prey on the ground rather than straight ahead.

However, many of them do have to move from one area to another during the course of the year because the food in one area becomes depleted or during their annual moult, they need a place where they are unlikely to experience any threats where escape through flight is necessary (since when moulting, flying is not ...
