Question

A bird shows two kinds of movements-upstroke and downstroke. During the
downstroke the wings are moved downwards and forwards. The air is pushed
down by the feathers, giving a lift to the bird. On the upstroke, the feathers are twisted open and the air is passed between the feathers. Thus much less effort
is needed in the upstroke than in the downstroke.
