the birds ' wings and feathers grew when thus before their bones were hollow or light.
While the wings of penguins are modified and no no longer useful for flight in air, they are NOT feeble. They ARE superbly adapted to flight in a different medium, that of water. Penguins use them to fly through water with GREAT efficiency.
Are Hollow.
The owls have adapted in various ways, becoming silent in their flight, able to see very well in both day and night and their ears have adapted to become excellent instruments, each adaptation has enabled the owl as a species to survive 58 millions years.

Birds don't necessarily need wind to fly. The flight can become easier when there is wind, depending on the circunstances, but that doesn't mean that a bird cannot fly in the absence of wind. It can become more tiring if the bird is adapted to flight with wind, but the movement of the wings still creates an upward and forward force that keeps the bird flying. For specifics about how do birds fly, search for that question.
living things are adapted! :]
yes, as well as a hollow bone structure
