From what the narrator tells us

In "A White Heron", the narrator takes more interest in showing the thoughts and feelings of 'Sylvia', a nine-year old girl, who lives with her grandmother, Mrs. Tilley, on a farm. She loves to go on a walk in the woods with her companion, Mistress Moolly, a cow. One day, while she was approaching back to her home, after her walk with Mistress Moolly, she was startled by a young hunter. She leads him to her grandmother, who offers a night stay as he was lost in the woods.
The hunter was looking to hunt "a white heron". Sylvia becomes friend of him, though she do not have much human friend, but with him she did. she loved nature, but this friend was in search to hunt a beautiful bird. She eventually finds the nest of white heron but she did not reveal it to the hunter. Disappointed he leaves.
So, at the end of the story, the narrator, addresses to the nature that Sylvia gave up her chance of gaining a human friend and to love a young man.
So, it is the narrator from whom the reader is able to get the glimpse of Sylvia's feelings for the hunter.
