The southern boobook is the most common and smallest owl on the Australian mainland. The sub species is characterised by its lighter colour than other sub species, and is generally found in a wide range of habitats (adapting very well to human activities). Ocellata is the smallest of the boobook subspecies as it is found in the warmer western parts of Australia (north-western New South Wales/western Queensland across to Western Australia). although it is not found in arid areas. The Boobook can be commonly known as the ‘mopoke’
Failure to refer Failure to refer Failure to refer, also reference failure or failure of reference, is the concept that names can fail to name a real object. According to Bertrand Russell's theory of truth, there is only one actual world, and a statement's truth value depends on whether the statement obtains in the actual world. Continuing the tradition of Gottlob Frege, Bertrand Russell posited that a name picks out, or refers to, a real object in the world (Russell's correspondence theory of truth). The name "Genghis Khan" thus picks out the 12th and 13th century Mongol leader we know by that name.
