why do some birds fly in a v formation?
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.

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.

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.

Cranes are in the order Gruiformes, along with rails and their relatives. Storks are in the order Ciconiiformes. ... Both cranes and storks fly with their necks outstretched, unlike similar-looking herons, which retract their necks in flight. Storks are more nearly related to herons than cranes are.

Yes, quite a little. Birds fly by flapping their wings in a pattern that both lifts and propels it. When it glides, however, its wings operate just like an airplane.

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.

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.

Aerodynamics. The V formation possibly improves the efficiency of flying birds, particularly over long migratory routes. All the birds except the first fly in the upwash from one of the wingtip vortices of the bird ahead. ... Canada geese, ducks and swans commonly form a skein in V formation.

Why birds fly in circles at sunset. ... One reason birds might circle round and round before roosting is to raise their body temperature, check out potential mates, or determine the hierarchy in group with the birds in the center of the flock and performing the best aeronautics being allowed the best sleeping areas.

In fact, hummingbirds are the only vertebrates capable of sustained hovering (staying in one place during flight), and they can fly backward and upside-down as well. To their maneuverability, hummingbirds add speed and stamina.

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.

Animals that fly can move through the air on their own, controlling their speed, direction, and height, and can stay in the air for long periods of time. Some animals glide through the air for shorter distances and for a shorter amount of time.

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.

If a bird is just gliding (or "soaring"), that is, not flapping its wings, it flies in pretty much the same way that an airplane flies. The wings push air down, so by Newton's third law the air must push them up. ... Birds use strong muscles in their breasts to flap their wings.

A big part of the reason birds are able to fly is because their wings create airfoils that can split the air. We also find airfoils in the shape of tiny wings on bugs or huge wings on airplanes. However, human arms are not good shapes for airfoils. As you've observed, even if you try to flap, you won't fly.

When birds learn to mimic human speech, it's because they think their owners are their flock mates and they're trying to bond with them. They're also very intelligent. So the short answer is because they have a different kind of vocal organ than other reptiles (birds are technically reptiles) and mammals have.

Loons swim well and fly adequately, but are almost hopeless on land, because their legs are placed towards the rear of the body. Three species have been recorded in Virginia.
