Der lange Weg (1990)

A beautiful seagull is injured during a storm, ends up in a forest and joins a family of woodpeckers. She is rejected by the older members, but the young woodpecker falls in love with her. So he leaves the forest at home and takes her to the sea, where the seagulls live. There the alien is also rejected. Now they are both looking for a land where they can be happy undisturbed. Several times we see a lonely seagull soaring over the waves of the sea and a woodpecker knocking on the trees of the nearby forest - before both find each other again in the community.
