Can Birds Fly on Mars?

An open-beaked bird appears perched on a rock, poised for flight. If this rock were a real bird, it would need to learn new ways to fly. It might be easy to lift off in the weaker gravity of Mars, but staying in flight would be hard. That's because Mars has a thin atmosphere and low air pressure.

Can birds fly in space?

A: Birds cannot fly in the vacuum of space because there is no air, but some birds have been brought to live on space stations before. American astronauts brought 32 chicken embryos to space on the Discovery STS-29 flight.
