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.
No. Both the cedar and bohemian waxwings are common birds.
Slow flying birds
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/
The term is "lift." It is created by the difference in air pressure between the upper and lower surfaces of the wing as the airplane moves through the air. This lift force allows the aircraft to overcome gravity and stay airborne.
Two main factors help birds fly: their own strength and propulsion. Birds use propulsion by turning their wings, lifting them upward, then turning them downward. As they lift the wings, air pushes up from below and pushes the bird forward.
Thrust is the forward motion of the airplane provided by the engines. Lift is the upward force on an airplanes wing.
The upward force due to a pressure difference is called lift. It is generated when the air pressure below the wing is higher than the pressure above the wing, creating a pressure difference that causes the wing to be pushed upward.
The upward force acting on the wing of a plane in flight is called lift. It is generated by the air flowing over and under the wing due to the shape of the wing and the angle of attack. Lift is essential for keeping the plane aloft and counteracting the force of gravity.
The upward force acting on the wing of an airplane in flight is called lift. It is generated by the flow of air over the wing due to differences in air pressure created by the wing's shape and angle of attack.
No, the upward force on an airplane wing is not thrust. It is actually lift, which is generated due to the pressure difference between the top and bottom surfaces of the wing as the air flows over it. Thrust is the forward force that propels the airplane through the air.
The upward force acting on the wing of an airplane in flight is called lift. It is generated due to the difference in air pressure between the top and bottom surfaces of the wing caused by the shape of the wing and its angle of attack. This lift force allows the airplane to overcome gravity and stay aloft.

Dont know maybe density force.
Perhaps coincidentally, most aeronautical engineers refer to that force as "lift".
The wing generates lift, which propels the aircraft upward due to differences in air pressure on the upper and lower surfaces of the wing. So, the wing is being pushed upward.
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.
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.
