Angelo by David Macaulay

From chapters.ca:
High above the rooftops of Rome, Angelo begins his work restoring the faade of a once glorious church. As with every project, he starts his final masterpiece by clearing away the years of debris left behind by the many pigeons who nest in the nooks and crannies of Rome's great architecture. There, among the sticks and feathers, he discovers a wounded bird. Finding no safe place to leave her, Angelo becomes the bird's reluctant savior. As the church nears completion, Angelo begins to worry about the future of his aviary friend. "What will become of you? Where will you go... where will you... live?" he asks her. Realizing what he must do, Angelo returns to the church to add one final finishing touch. Through his artistry as a master craftsman he answers the questions about his humble friend and assures that he will not be forgotten. With his expressive illustrations, filled with detail and humor and infused with the warm, terra- cotta glow of the Mediterranean, David Macaulay will once again capture his readers" hearts and imaginations with this poignant story of enduring friendship.
