why do birds fly in a v form?
1703
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.

The (more or less) hollow and chambered bones of birds reduce mass, allowing flight with less power needed and provide even more space for inclusion of air exchange sacs. So, the pathway in which birds developed simply did not need or require the enucleation of RBCs to accomplish certain metabolic demands.

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.

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.

Soaring birds take advantage of thermals and updrafts by flying in a circle. The rising air carries them higher and higher in a spiral. ... Soaring birds that wish to stay aloft without flapping in normal wind usually fly INTO the wind for lift. But that same wind that holds them up slows their forward movements.

To do this, birds use wings with light, hollow bones and feathers on them. ... Birds can move by flapping their wings, or they can stay in the same place. This is called hovering, with rapid wing beats, as with the kestrel. Birds that soar use very little energy for it: they use columns of rising hot air to lift them.

Though bat have wings,bat is a mammal because they are warm blooded, give birth to young ones and have fur and produce milk. Because it flies we can call it as a aerial animal just like we call a car which could fly as a flying car or a aerial car. so bats can be referred as aerial animal.

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.

Birds obtain thrust by using their strong muscles and flapping their wings. Some birds may use gravity (for example, jumping from a tree) to give them forward thrust for flight. Others may use a running take-off from the ground.

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.

The bodies of birds are adapted for flying. ... The long flight feathers on the wings and tail help birds balance and steer. In addition, birds have a system of air sacs in their body that connect to the lungs. The air sacs enable birds to extract much more oxygen from each breath of air than other animals can.

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.

There actually are simple... Birds that fly across oceans such as albatrosses have very long wingspans and they seldom need to flap their wings; they simply glide most of the way. ... Inland species usually don't stop flying until they reach their destination, and the smaller ones may be very exhausted after the journey.

Why can't birds fly in a vacuum? A: Birds generate lift by using Bernoulli's principle just like an airplane. ... Without air, like in a vacuum, it is not possible to generate low and high pressure around a wing and so the bird cannot achieve lift.

They can fly in light rain, but they don't like to. They use the sun for navigation, so cloudy, wet weather isn't their favorite thing. A heavy rain can make their wings wet, slowing them down. If the raindrops are really big, they can break a bee's wing.

Researchers have finally been able to explain the reasons for birds flying in the "V" formation when flying in flocks. ... The downward motion tends to push the following bird down and hence it is avoided, whereas flying slightly above the leading bird gives an upward motion, that is advantageous to the following bird.

Read below for information on 3 different animals that start with the letter V. They are the vampire bat, the vervet monkey, and vulture. ... Vervets are mostly tree dwelling animals. The vulture is a carnivorous bird that is widely distributed across the world.
