A bird flies in a straight line directly over a field. Does the bird have angular momentum with respect to a man standing in the field?

Yes.

Does the man have angular momentum around the bird?

Yes.

Do they have *net* angular momentum around their common center of mass?

No.[EDIT] More precisely, the net angular momentum is zero if you consider the man-bird-field system to be closed, and ignore the gravitational attraction between the man and bird.

Why?

Because angular momentum is conserved.

Now I have a question? Why was this posted to the Quantum Mechanics forum?
