The Lord God Bird Is Officially Extinct on the First Day My Brother Seeks Treatment.

The text centers on the extinction of the Lord God Bird, a species last documented in 1944, and parallels this loss with the mental struggles of the narrator's brother, who is grappling with intrusive thoughts and seeking treatment. The Lord God Bird's extinction is attributed to habitat loss from logging, though it persisted in folklore and disputed video evidence. The narrative explores themes of delusion, devotion, and the haunting persistence of loss, using the bird's disappearance as a metaphor for the brother's deteriorating mental state. Historical descriptions of the bird by Audubon emphasize its fierce nature, contrasting with the brother's vulnerability.
