In Their Eyes Were Watching God (which is a fantastic book that is also [shameless plug] a proposed topic challenge), there's a strange scene on pages 61-62 where several vultures (a type of bird) start talking:
He finally lit on the ground and walked around the body to see if it were really dead. Peered into its nose and mouth Examined it well from end to end and leaped upon it and bowed, and the others danced a response. Tat being over, he balanced and asked:
"What killed this man?"
The chorus answered, "Bare, bare fat."
So he picked out the eyes in the ceremonial way and the feast went on The yaller mule was gone from the town except for the porch talk, and for the children visiting his bleaching bones now and then in the spirit of adventure.
It's strange because, I think aside from possibly one other scene in the beginning of the book, it's the only time animals speak in the book. And as far as I can tell this isn't a particular theme of the book. So what's the point of including a page long scene where animals speak?
