If we tie light oxygen tank to a bird so that it can breathe on moon, would the bird fly faster, slower or same speed?

Question

If we tie a light oxygen tank to a bird so that it can breathe on the moon, would the bird fly faster, slower, or the same speed as it does on earth? (Remember that there is less gravity on the moon.)

Answer 1

Bird flys by displacing the air with its wings. The reactive force generated in absence of atmosphere is zero. hence the bird will not be able to fly on moon.
