"The Fisherman and the Bird" by Sonia Levitin

Rico has lived and fished alone since being jilted in his youth. But one day, Rico discovers that a pair of beautiful birds have built a nest at the top of his mast. He is ready to destroy the nest so that he can sail, but the local school-teacher convinces Rico of the rarity of the birds and the importance of letting them nest. Begrudgingly, Rico leaves the nest undisturbed and is transformed by the their beauty and the friendship of the villagers.
