07. Could birds survive in space? With no air, could they fly? (A K2S Question)

From The Space Library

Birds require air to breathe and they use the development of pressure difference on the two sides of their wings to fly. In the absence of air, it would not be possible for birds to breathe or fly. The outer space between the different bodies of the Universe is largely a vacuum. Therefore birds cannot survive in outer space. However, many planets such as Mars and Venus have atmosphere and air—albeit extremely different from that on Earth. If the temperature, pressure and constituent gases become similar or identical to those on Earth, birds may be able to fly there too. In addition to the above-mentioned factors, prolonged exposure to micro-gravity or no gravity can induce changes in the bone structure and anatomy that may alter their flying capability. Not many experiments involving birds have been carried out by the ISS.
