Slow flying birds
A flying bird's wing is in the shape of an airfoil.
When flying, the birds need power on the wing to fly. Their bodies should also be streamlined.
A penguin does not have wings like other birds. Instead, they have flippers, with massive, short and flattened. Bones. For a penguin the wing-beat in the water is similar to those by flying birds.
Pigeons do not defecate on the wing, but must be landed to defecate. Their legs grip the base of the tail during flight to increase streamlining, and means they cant defecate on the wing as other birds do, such as seagulls.

A flying wing is essentially an airplane with the fuselage missing or embedded into the wing. The aircraft appears to be largely just a wing. The B2 bomber is a flying wing. There are other examples. The ultralight of many years ago called the Mitchell Flying Wing was a wing with the pilot slung underneath. There are other examples. They tend to have control sensitivities in the directions of pitch and yaw. Computers and active control surfaces assist in controlling the B2.
An example of an analogous structure is the wings of birds and the wings of bats. Both structures have a similar function (flying) but are made of different materials and have evolved separately in these two distinct groups of animals.

Without wings, birds couldn't fly.
