The story of "The Scarlet Ibis" is told by Brother. He never gets an actual name and is called "Brother" throughout the story. Brother is the older brother of Doodle. In addition to who the narrator is, I would like to comment on the point of view of the narrator. The narration is being told from the first person perspective. Brother puts himself back into the narration via "I," "me," and "us." This limits the audience's knowledge of events, because readers only get to know about what is going on inside of Brother's head. A reader can only know about other character's thoughts if that character speaks what he/she is thinking. The last narrator detail that I would like to mention is the fact that Brother is narrating this story many years after it happened.
It's strange that all this is still so clear to me, now that summer has long since fled and time has had its way.
He is a fully grown adult, and he narrates the events in hindsight. Because of that, the story functions a bit like a warning or moral lesson story.
