Answer:
At the end of the story, Sylvia climbs the tall pine tree and sees the white heron perched on a high branch. She hears the hunter calling for her to join him and tell him the bird's location. Sylvia is overwhelmed by the beauty of the bird and the tree, and as she looks out at the landscape, she realizes that she cannot betray the bird's trust.
In the final moment of the story, Sylvia descends from the tree and tells the hunter that she cannot reveal the heron's location. She knows that the hunter will be disappointed, but she feels a sense of peace and satisfaction in her decision to protect the bird's life.
