which is the only bird that can fly backwards and hover?

Hummingbirds can fly right, left, up, down, backwards, even upside down due to their special wings. Hummingbirds are also able to hover by flapping their wings in a figure - 8 pattern.   http://www.kidsplanet.org/factsheets/hummingbirds.html

In simple terms, it is like a thumb for birds, it helps control their flight.\n\nIf you are looking for a more complex answer...see below:\n\n"The alula, or bastard wing, is a small, feathered projection on the anterior edge of the wing of modern birds. It is actually the thumb of the bird, and has been modified into an aerodynamical control device not too dissimilar from the forward slat on an airplane wing. Usually flush against the wing, the alula may be moved to modify the shape of the wing or provide a slat for direction of airflow, often to avoid stalling while landing. It has been found in all modern birds since Eoalulavis hoyasi, a primitive bird from the mid-Cretaceous, 115 million years ago."

Regardless of the way of movement, peregrine falcon is the fastest. If you are trying to ask the fastest by way of running then cheetah is the fastest.\n\n>>The fastest animal/ bird is called peregrine falcon which can fly at the speed of 100-200 miles per hour. \n>>Fastest marine animal is blue whale which swims 30 miles per hour).\n>>Fastest land animal is cheetah which can run 70 miles per hour. \n>>Fastest fish is sailfish which can swim 68 miles per hour. \n>>Fastest insect is dragonfly which can fly 36 miles per hour.♥

If it has wings it's a "fly"\nIf it doesn't it's  "grounded"!!! \nThat was a cute question. I'd never thought of that....LOL ;o)

Um. . . .they both have wings and they can fly. :)

They will stay on the ground regardless of the speed. They are not aerodynamic, so they won't naturally rise in the air and fly because of speed unless they had wings added to them.

Chickens can barely lift off the ground, since they lost the ability to fly through centuries of breeding, but ducks can fly at 64 km/h, and travel thousands of kilometres!

A wonderful bird is the pelican,\nIts beak can hold more than its belly can.\n\n:)

I just saw one right now, it's flying in the air!\n I think I'll go shoot it for dinner!  \nThanks for the duck!\nBye!

From what I have been able to find on the subject, the shuttle cock must have all the feathers from the same wing of the bird in order for it to spin correctly to stabilize in flight.  Since all feathers must come from the same wing, someone at some time decided to use feathers from the left wing.  i suppose they could have selected the right wing just as well but they had to select all their feathers from either the left or the right and somehow the left was selected.

The hummingbird will start moving backwards because the plane is accelerating and unless the bird is moving forward, the bird's inertia will have it attempting to stay in place which is moving backwards.\n\nBut if you're talking about a non-accelerating plane that is moving at a constant velocity then the bird will stay in place.

What Kind Of Bird Are You Talking About?  The Finger Or Big Bird?

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.

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 birds bones are lighter and hollowed out.  The feathers are lighter then human hair.  There bodies are streamlined similar to an airplane.  Depending on what kind of bird,  these adaptations may vary.  An ostrich is much heaviar then a falcon.  A falcon is much like a fighter jet, it is built for flight and speed.  They achieve high speeds by having thin wings and light bones,  many birds are built in this way and some may not fit the category.  Some are not built for flight.  But these adaptations are set to make different birds greatly adaptable to there surroundings.

You mean their is one that can fly.

All thing that flies except aeoroplane.
