A: Wings need to be curved to achieve lift. The curve forces the air above the wing to speed up, and according to Bernoulli's principle, faster moving air exerts lower pressure than slower moving air.

Why do birds have curved wings?
The feathers on a wing are flexible, so the feathers at the end of the wing separate as air moves over them, reducing the drag on the wing. Flight feathers are also asymmetrical and curved, so that air flowing over them generates lift.
Does a swift sleep on the wing?
Except when nesting, swifts spend their lives in the air, living on the insects caught in flight; they drink, feed, and often mate and sleep on the wing. Some individuals go 10 months without landing. No other bird spends as much of its life in flight. ... Their maximum horizontal flying speed is 111.6 km/h.
Why are wings shaped the way they are?
Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.
Is a swift a real bird?
swift, any of about 75 species of agile, fast-flying birds of the family Apodidae (sometimes Micropodidae), in the order Apodiformes, which also includes the hummingbirds.
Why do birds have different shaped wings?
The shape of the wing is important in determining the flight capabilities of a bird. Different shapes correspond to different trade-offs between advantages such as speed, low energy use, and maneuverability.
Can a human fly?
Humans are not physically designed to fly. We cannot create enough lift to overcome the force of gravity (or our weight). ... Their light frame and hollow bones make it easier to counteract gravity. Air sacs inside their bodies make birds lighter, which enables smoother motion through air.
What bird stays in the air for 5 years?
The Common Swift Is the New Record Holder for Longest Uninterrupted Flight.
Where do swifts go when raining?
Swifts will take shelter in their nests in heavy rain, even staying in for much of the day. I have watched them flying in front of and away from an approaching heavy thunderstorm. Local storms are regularly dodged in this way.
Can a bird sleep while flying?
Migrating birds may also rely on USWS to rest. The long migration flights of many species don't allow for many chances to stop and rest. But a bird using USWS could both sleep and navigate at the same time. There is evidence that the Alpine Swift can fly non-stop for 200 days, sleeping while in flight!
Do planes have rudders?
The rudder is used to control the position of the nose of the aircraft. Interestingly, it is NOT used to turn the aircraft in flight. Aircraft turns are caused by banking the aircraft to one side using either ailerons or spoilers.
Why are wings of Aeroplane rounded outward while flattened inward?
A: Airplane wings are often curved on the top and flat on the bottom, which makes them look teardrop shaped! This is because of Bernoulli's Principle. Bernoulli's Principle states that faster moving air has lower air pressure and slower moving air has higher air pressure.
Why are airplane wings shaped like airfoils?
An airplane's wing has a special shape called an airfoil. The airfoil is shaped so that the air traveling over the top of the wing travels farther and faster than the air traveling below the wing. Thus, the faster moving air above the wing exerts less pressure than the slower moving air below the wing.
Do swifts have white bellies?
They can often be seen visiting puddles to collect the mud they use to build their impressive nests. Key features to look for are the white rump and the all-white underparts, with no dark band across the breast.
How long does a swallow live?
The average lifespan is 3 years in the wild.
Swallows come in a variety of shapes, sizes and colors. Their body length ranges from about 10–24 centimeters (3.9–9.4 in) and their weight from about 10–60 grams (0.35–2.12 oz).
Do swifts make a mess?
Fully protected by UK and EC laws (it is illegal to kill or harm them, to damage their nests or take their eggs) Swifts do no harm, make little or no mess. They eat flying insects such as aphids, flying ants, mosquitoes, hoverflies and small beetles, catching huge numbers every day.
