"The Scarlet Ibis" is not one of those stories that has an obvious setting; however, there is overt reference to the setting throughout the story. In particular, the story occurs in and around the family home in Southern America, obviously in and around the surrounding countryside based on the author's descriptions. Remember, too, that setting is more than where a story takes place, and this story takes place during the "blighted" summer, with the hurricane bringing down trees and ruining crops." In addition, the devastation of the setting seems to foreshadow the destructive effects that Brother's pushing Doodle beyond his limits.
