why does a flock of birds fly in a circle?
242051
Why do flocks of birds fly in a circle over the same place over and over again? The behavior you speak of is due to an effect called thermals. ... Social birds that fly in large flocks also use thermals to gain altitude and extend their range during migration.

Researchers think that the honking sound geese make as they fly is used to help maintain the integrity of the flock, and to co-ordinate position shifts with the V-formation in which they fly. But for geese, honking one's position is a trade-off that helps helps save energy for the flock as they fly.

"There are two well-supported and complementary explanations for why birds fly in formation. One is to conserve energy by taking advantage of the upwash vortex fields created by the wings of the birds in front. The other is to facilitate orientation and communication among the birds."

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.

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.

Other than a few differences such as air sacs connected to their lungs to make them lighter and a lightweight skeleton with hollow bones, birds can fly because their wingspan and wing muscle strength are in balance with their body size. When it comes to us humans, it's all about strength to size ratio.

When a bird hovers, it is flying, but not moving through the air; when a bird windhovers, it is flying through the air, but it is flying upwind at the same speed as the wind. ... Strictly, windhovering is not hovering, but it is an interesting tactic used by some birds to temporarily hang over one spot.

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.

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.

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.

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. There are two reasons birds might fly in a V formation: It may make flight easier, or they're simply following the leader.

Many birds fly in the dark during migration without any specializations to their eyes. Some stay in touch with vocalizations. and positioned at the front of the head. The eyes have a field overlap of 50–70%, giving better binocular vision than for diurnal birds of prey (overlap 30–50%).

Most birds can fly, at least short distances, in the rain using the oil to protect their feathers. However, in particularly heavy rain their wings may eventually get saturated with water making it difficult to fly and leaving them more vulnerable to predators.

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. Flying also helps them travel from cold places to warm places, called migration (my-GRAY-shun).

Birds don't always have to flap their wings to fly. Once they're up high in the sky, they can also glide, which is kind of like getting a free ride on the air. They only have to flap their wings once in a while. They can also let a jet of air push them up even higher, to the tops of really tall trees.

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.

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.
