* Some wings help bats
  - owls
* Some wings make noise
  - whistle noise
  - move insects
* allow aphids to disperse to other plants when the quality of the food source deteriorates.
* also help produce another force, called thrust, that pushes the bird forward through the air.
* are a membranous outgrowth of the body wall and contain no muscles
  - physical adaptation of bats
  - very special adaptation of bats
  - air units
  - airfoils
  - far more than feathered arms
  - held horizontally to the body in dragonflies and vertically in damselflies when at rest
  - helpings
  - insignias
  - limbs
* are located in airplanes
  - birds

  - large buildings
  - mansions
  - magazines
  - means
  - mechanical devices
* are part of airplanes
  - division
  - south parks
  - the endoskeleton of an insect
  - positions
  - simply the side petals, which sometimes spread away from the blossom like wings
  - social groups
  - stages
  - supposed to have evolved in at least four different groups as analogous structures
* are the lift- producing part of the aircraft
  - very books in which the identities of many insect groups are written
* are used for aircrafts
  - bugs
  - eating
  - flappings
  - flying
  - glides
  - raises
  - soaring
  - video games
* blending into body feathers or being held away from body are undesirable.
* can meet in flight under the body, during courting displays.
* cause aerodynamic lift.
* create musical sound
* extend beyond abdomens.
* grow big as their load increases.
  - lead edges
* have similar bone structures
* help birds fly and keep their balance.
  - quill feathers
  - sections
* look like chicken wings
* move air downward, and react by being pushed upward.
  - same functions
* provide the majority of the lift for an airplane, but wings also cause drag
  - for the airplane, but they also cause drag
* refers to improvements in curriculum and instruction designed to let children soar.
* serve functions.
* symbolize flying, lightness and expansion.
+ Fixed-wing aircraft, Parts, Wings: Aircraft :: Aerospace engineering
  * Some wings have panels on the back called flaps. Flaps can be extended to make the wing bigger. This makes the wing make more lift, but also more drag. This lets the plane fly slower without stalling, so flaps are often used during takeoff and landing.
+ Scissor-tailed flycatcher: Passeriformes :: Symbols of Oklahoma
  * The nape of its neck and its back are pearl gray, and the breast is white. Wings are sooty black with a touch of scarlet at the shoulders. The principal threat to scissortails is poaching. A great number of birds have been killed by poachers who wanted only the bird's tail.

Bird wing
* are airfoils, which have shapes that create lift by altering air currents.
* consist of feathers extending all along the arm.
* flap, eats cheese, sings, and whistles.

Broad wing
* Most broad wings have feathers
* give a bird a good lift for slow flight or for rapid takeoff.

Butterfly wing
* Some butterfly wings have spots that look just like eyes.
* are delicate ,go slowly but firmly,use always the same hole
  - exceptional in the complexity and diversity of their color patterns
* symbolize joy and eternal life.
