Question

the number of degree of freedom for birds that fly in space

Answer 1

-well, if birds were taken to outer space, they would float around, not fly
-and unless someone made those birds some little spacesuits, they would die
-space has no pressure, so the tissues and organs of those birds would just sort of disintegrate 
-and dead birds don't really have any freedom, do they now? I guess they'll have freedom from life...
