It is called Lift. The difference in pressure above and below the wigs as a bird moves through the air produces an upward force that causes the bird to rise.

Are wax wing birds rare?
No. Both the cedar and bohemian waxwings are common birds.
How many toes do red wing black birds have?
The red wing black bird has three toes
What has more lift - the wing of a slow-flying bird or the wing of a fast-flying bird?
Slow flying birds
What causes a bird to fly?
A wing creates lift by imparting a downward momentum to the air flowing above and below it. The rate of change of momentum is equal to Force (Newton's 2nd law), and therefore a reaction force pushes the wing up, producing lift (Newton's 3rd law).The act of imparting a downward momentum ("downwash") to the air results in an air pressure differential around the wing. If you know the pressure above the wing and the pressure below the wing, and the wing area, you can calculate the lift force on the wing since Force = Pressure x Area. If you don't know the pressures, you can get a rough estimate if you know what the average air velocities are above and below the wing. By employing Bernoulli's Principle, you can calculate a pressure difference corresponding to the difference in velocity.Note that there is no requirement that the air molecules separating at the leading edge and flowing below the wing meet up with the same molecules that flow over the top. This is called the "equal transit time theory" and is a popular science myth that unfortunately has found it's way into flight manuals and even some undergraduate texts. However, aerodynamicists have known ever since they started doing wind tunnel testing that the air flowing over a lifting wing reaches the trailing edge sooner than the air below it. This can be explained in terms of the circulation theory, which is an advanced concept.Please see the excellent link below for more information:http://www.av8n.com/
Why do ducks make an arrow when they fly?
From " = Why do birds fly in a v?" = The reason they fly in such a shape, is so that one can take the lead, and when it gets tired, it can fall back and another will take it's place. Also, the formation helps the other birds save energy by flying off the "disturbed" air that the lead bird is creating, and they can ride off of it and not get worn out so much. When a bird flies, the air above and below its wing get "shifted" out of place, and it creates an upward current. By riding off that current, a bird behind it can save energy. The V shape comes from birds riding off each others current, since the outside wing will stick out more than it's body, birds will place themselves right behind the outside wing.
Is the upward force on a airplane wing is thrust?
Thrust is the forward motion of the airplane provided by the engines. Lift is the upward force on an airplanes wing.
What is the upward force due to a pressure difference between the top and bottom of a wing?
The upward force is called lift.
Is the upward force on a airplane wing a thrust?
No. We call the upward component of force "lift"."Thrust" is the component of force forward ... the direction the plane's nose points.
The upward force acting on the wing of an airplane in flight is called?
Lift.
What is the upward force on a wing as it moves through the air?
Perhaps coincidentally, most aeronautical engineers refer to that force as "lift".
What is the upward force due to fluid flow around an airplane wing?
Dont know maybe density force.
What is the upward force acting on the wing of an airplane in flight?
It's called "lift" and is the difference in air pressure between above and below the wing.
Is the wing being pushed upward or downward?
Upward
How do you birds fly is gravity pulling them to the ground?
Birds fly in air. They use the air to fight gravity. When air travels faster along the upper wing than the lower wing, the air force down is less than the air force up -- really helps most birds. Gravity affects birds.
How do birds fly when gravitational pull is pulling them down?
Gravitation pulls everything down (people, rocks, birds, planes..) It takes a force to counter the pull of gravity; in birds' case, it's lift from the birds wing. As air flows past the wing the fact that the length of chord of the upper wing is slightly longer then the length of the chord of the bottom of the wing - this induces a difference in flow speed and creates a slight upward force called lift. The faster a bird goes, the higher the lift (to a limit.) The longer the wing, the more lift is generated - this is why bird with very long wingspans can travel long distances and go very high compared to birds with shorter wings.*If a bird's wing cannot generate enough lift, the bird will fall to the ground: they must overcome the pull of gravity. * Note - high speeds are counter to large wings, hawks have shorter and swept vs broad wings on Eagles. The Eagles can go higher and longer, but the Hawks can go faster for short periods of time.
What makes an airplane lift off the ground?
An airplane lifts off the ground because of the upward force created by the difference in pressure from the upper and lower part of the wing. The air travels faster over the top of the wing than the bottom of the wing because of the wing shape. This creates a low pressure on the top of the wing and high on the bottom. This can be explained better by understanding Bernoulli's Principal. The pressure difference causes and upward force on the wing which creates lift which allows the plane to lift off the ground.
What causes awing to lift?
The aerofoil shape of a wing is designed so that the speed of air flowing above the wing is faster than that below. This creates an upward force, called lift.
