A treatise on bird watching was owned by the Human thief, Reki, during the Cold War. He kept the book in his house in Mannett Point, on the planet of Ord Mantell. Reki used the book to conceal schematics to a warehouse near his home, which he frequently stole from. To access the schematics, every mention of the Mantellian flutterplume, a type of bird included in the treatise, had to be replaced with the number "3". Reki considered the book to be incredibly boring.
