Dayton Castleman's Bread Bird

I like this small piece made from bread and steel by Dayton Castleman. Titled “Bread Bird,” he succinctly explains:

An inquiry as to whether birds would eat bread in the shape of their own. In this case, Chicago pigeons would not.

I’m curious to see this experiment repeated with different food types. I hypothesize that birds wouldn’t think twice about eating a fellow bird made from bacon.
