Why do birds fly  V shaped sometimes??

A team of scientists taped heart monitors to a group of pelicans that were trained to fly behind a small airplane. They discovered that the heart rates of the birds were lower when flying in a V than when flying solo. Migrating birds use the "squadron" formation because it allows them to glide more often, conserving energy. The aerodynamic V shape reduces the air resistance, allowing the geese to cover longer distances. In fact, a flock of geese can fly 70 percent farther by adopting the V shape rather than flying in isolation. \n\nThe V formation may offer other benefits as well. Each bird has an unobstructed field of vision, allowing flock members to see each other and communicate while in flight. \n\nThe goose at the head of the V is not necessarily the leader of the flock. Apparently, geese take turns leading. As one bird tires, it drops to the back of the formation and another takes its place. Now that's what we call teamwork.

it shows the direction that the wind is coming from. \nthis is because it normally has a huge tail and a small head. the wind blows the huge tail, and the head points towards where the wind is coming from.

I'd think that birds that land on water by skidding on the surface before stopping might have inspired the conventional aircraft landing made with shallow descent and rollout. On the other hand people like the Wrights may have just figured that out for themselves. \nSome landing styles not yet emulated by planes: Braking to a stop and grabbing hold of a branch, and diving into the water!

They buzz not by choice and by choice at the same time... Who wrote that  they buzz because of their wings beating is correct but bees and wasps can buzz in a different frequency and/or fly in determined angles to indicate food sources and to indicate danger!

Some birds will fly away from their nests as a way to distract a threat. Or they will fly at a predator in an attempt to annoy them. If they're large enough or persistent enough, they may also use their beak or feet/talons to cause injury.

If you look at the shape of the wings you will notice that they are not 'flat'.  They have a unique shape to them.  The shape forces the air that flows below the wing to travel faster than the air above them, which pushes up on the underside of the wing, otherwise known as 'lift'.

because of gravity, pulling inward with the same force in all directions, giving them a round shape.\n\nyou look very pretty in your avatar by the way ;)

To look like it is flying.

Generally it's called a V formation, and it's usually geese (Canada geese are common geese that you'd see). Ducks also fly this way, although I usually see them in pairs.\nBirds fly this way because it's more aerodynamic. The bird in front is essentially plowing the way through for the rest of them. The ones behind fly in its "wake". They take turns being the lead bird since that's the hardest position to be in.

a bird can fly but a fly can't bird.

The same reason airplanes do. Its a matter of lift and drag, based on the shape of the wing. A frisbee is just a circular wing.

Birds and fowl lack smooth muscles in their throats to pull food and water down to their stomach.  Therefore they have to lift up their heads and let it fall.  This is why you can't bring a canary in outer space because it would starve/dehydrate.

These birds do not all have the same foot posture.  For example ostrich feet sit flat on the ground for walking while songbirds toes are designed to be able to curl and grip branches when they perch.  Birds like eagles have raptorial feet with long talons for capturing prey.  \nHope this helps

Almost all migrating birds fly north in the Spring, unless they are from the other side of the equator. Then they fly South. They fly in order to see the daffodils, hyacinths, azeleas, etc. They also fly north to find clean cars to mess up.

They fly and land a lot like pigeons, so I don't think they have a distinctive flight pattern.  At least, not distinctive enough to notice.  It's probably more that it's easy to spot a dove in flight (because it's white) rather than the way it flies.

It just means that a bird flew by
