From their speed and wings combined.
Overall they work like an airplane, except they get their speed from clapping their wings.

What does the difference in air presssure above and below a birds wing cause?
The difference in air pressure above and below a wing causes lift. The lift creates flight. The result is that birds fly.
What bird can lift the highest weight?
Birds do not lift weights.
Are birds wings flat for increasing lift?
If they were flat they would generate no lift and birds could not fly. Aeroplane wings are very similar in shape to bird wings - they are nearly flat underneath and convex on top.
Will a lorry with birds on it weigh the same if all the birds lift up in the air?
If the lorry contains the birds in a sealed container then the weight is unchanged. As they lift from their perches they must accelerate and the resultant downward force on the lorry will make it appear to weigh more for a very short time.
Which feather is important for flight?
The large one on a birds wings; they produce lift.
What special designs do birds have that enable them to fly?
Birds have hollow bones, and that makes them light enough for their wings to lift them off the ground. Also they have wings and lots of feathers, and they are shaped to give the bird lift so it can fly.
Why do birds push the air downwards with their wings?
so they can gain lift so they can fly
How many swans are lift?
swans the birds - approximitly 50,000 all over the world
What is the function of birds tail?
the function of a tail is to lift its body and to increase the speed of flight
The feathers of birds serve two primary functions?
lift for flight and conserving heat
How is lift generated in a birds wing?
When in flight, birds flap their wings to push air beneath them. By pushing the air down, they are propelling themselves upwards.
How does mass affect flight?
There is a reason birds fly and pigs do not. Birds have hollow bones and are light. The lift of the wings can support their light weight. Pigs have heavy bones and do not have the strength to either jump or lift in their appendages to support their weight. In airplanes, a heavy airplane, C130, must have more lift in the wings than a light airplane.
