how do birds fly together?

When birds fly in flocks, they often arrange themselves in specific shapes or formations. Such formations, which can take the form of a 'V' shape, often take advantage of changing wind patterns based on the number of birds in the flock and how each bird's wings create different currents.

Flocking also enables birds to fly further using less energy because when the strong leader bird flaps its wings it creates uplift for the birds behind – each bird (except the leader) is flying in the up-wash from the wing of the bird in front. This enables the flock to use less energy and reduces fatigue.

Hummingbirds are the only birds that can fly backwards and upside down. The design of a hummingbird's wings differs from most other types of birds.

The one thing that distinguishes birds from all other animals is feathers. Other animals are warm-blooded (mammals), lay eggs (insects and fish), or have wings (insects and bats) but only birds have feathers and all birds have feathers. Feathers are used for flight, temperature control, and attracting a mate.

How can birds fly when it rains? Birds fly by forcing air downwards with their wings. On the upstroke, the feathers pivot to let the air pass through them, but on the downstroke they close – similar to a venetian blind – and push against the air. When it rains, the same principles apply.

Although some crows are solitary, they come together in groups for feeding, roosting, and social interaction. For instance, when one dies, the group will surround the deceased, circling, and cawing to both mourn the dead and find out what killed their feathered friend.

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.

Other animals are warm-blooded (mammals), lay eggs (insects and fish), or have wings (insects and bats) but only birds have feathers and all birds have feathers. Feathers are used for flight, temperature control, and attracting a mate. Most birds can fly but some like the Ostrich, Penguin and Emu cannot.

The wing structure of bats and birds differs. Birds have feathers projecting back from lightweight, fused arm and hand bones. Bats have flexible, relatively short wings with membranes stretched between elongated fingers.

The only animals that can truly fly are birds, insects, and bats. Other animals manage to travel through the air by gliding from great heights or leaping from the depths.

Birds, including starlings, mostly fly in flocks as a defence against birds of prey. The more individuals in a flock, the less risk for each bird of being the unlucky one who gets taken out by a hawk or another raptor. But starling flocks also fly in such formations when no predators are around, according to Dale.

Others prefer to set off together in large flocks, for example the starlings and swallows. Geese, pelicans, storks and other larger migratory birds fly in a straight line, a chain, or the so-called V-Formation, also called wedge-formation. The reason for this is simple: aerodynamics. The birds want to save energy.

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.

A. Unlike humans, bird bodies don't store fat. Fat, like their muscles, bones, and internal organs, have weight, and birds need to keep an ideal body weight in order to fly. So on a day-in-and-day-out basis, birds eat on an energy-in-energy-out basis.

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.

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.

Birds have strong and powerful wings that help to lift their entire bodies off the ground. These are special adaptations that help them fly. The shape of birds' wings and the way they flap them allows air to move much faster above the wing than below the wing as they soar into the air.
