A flying bird's wing is in the shape of an airfoil.
Slow flying birds
the birds wing is hairy and the insects wing is delicate
The wing of a bat. The leg of a horse...
the shape of the wing is airfoil. basically this is what helps it go smoothly through air...http://amasci.com/wing/airfoil.html
A bird's feathers are specially designed to be lightweight, yet strong and flexible. They help create lift and thrust during flight by providing a large surface area for air to push against. Additionally, feathers help birds to control their speed and direction while flying.
Different bird species have adapted to their environments over time, resulting in wings with varying shapes to suit different flight patterns and behaviors. Wing shape influences how birds maneuver in the air, such as for soaring, diving, or agile aerial movements. Birds with long, narrow wings are better suited for gliding and soaring, while those with shorter, rounded wings are more agile for quick and precise flight.
The shape of a bird's wing, with a curved upper surface and flat lower surface, creates a pressure difference between the top and bottom. When the bird moves its wings through the air, a higher air pressure below the wing pushes the bird up due to the pressure difference and creates lift. This lift helps the bird to fly.
Without wings, birds couldn't fly.
Feather
A small white bird with black wing tips is likely a seagull. Seagulls are known for their white feathers and black wing tips, which help them stand out against the sky. These birds are often seen near bodies of water and are known for their scavenging behavior.
A bird's wing is shape like an airfoil. (See the related link Diagram of an airfoil below.) The airfoil is curved more on top, so the air flowing over the top of the airfoil moves faster that the air underneath. This creates more pressure underneath the wing, pushing up and generating a force called lift. This force keeps the birds in the air. (This is also how the wings of an airplane work.)
