The Song of the Ape: Understanding the Languages of Chimpanzees, by Andrew R. Halloran; published February 28, 2012, by St. Martin's Press; "In these ice-skating shows, the 'amazing ice-skating chimpanzee' (who was usually billed as an adult male) was actually several different juvenile female chimpanzees. Different females would travel to different locations and star as the billed ice-skating chimp. Because of this, it is difficult to pinpoint exactly where Little Mama had performed. The events I've just recounted come from an amalgamation of reports of many different ice-skating chimpanzee performances (any number of which may have been Little Mama)."
