Bat's wings are the equivalent of the human arm. The bats fingers are highly elongated to produce the wing tip as well as support for the wing's membrane. The forearm provides wing length on the far side of the elbow that can be folded back against the upper arm (humerus) when they are at rest.
Homologous, meaning they have adapted the same structure (in this case, the mammalian foreleg) to perform different functions.
The only mammals with wings are the Bats. Bats have a pair of wings.
Pigeon wings are derived from an ancestral limb: the forearms. Butterfly wings (and other insect wings) are novel appendages not derived from other limbs. They are actually derived from an outgrowth of respiratory tissue.

Bats are not birds as they have no feathers, talons, beaks, or any organ specifically related to birds. The bat's wings are also not the same style as bird's wings. Bats seem to have the same structure in their wings as the human hand. And, they do not lay eggs, they give live birth.
Birds and bats are born with effective wings they do not create them. These animals are born with effective wings to transport themselves efficiently in the world.
