(Strigidae; Ϯ Tawny Owl S. aluco) L. strix, strigis  owl, screech-owl believed to suck the blood of infants  < Gr. στριξ strix, στριγος strigos  owl; "42. STRIX.  Rostrum aduncum (absque cera) basi pennis setaceis tectum.  Caput grande auribus oculisque magnis.  Lingua bifida.  ... Strix differt a Falcone ut Phalæna a Papilione; altera enim diurna, alter nocturnus est. Noctu prædantur aviculis, muribus; die cæcutiunt; pedes lanati ne frigescant; aures amplæ ut percipiant; die aviculis opprobrio expositæ." (Linnaeus 1758); “The type of the genus Strix has by most English authors been considered to be S. flammea [= Tyto alba] of the 12^th edition of Linnaeus. This species, however, is not found in the 10^th edition, so that it is necessary to find a type among the species which are included in that edition. An examination of Linnaeus’ descriptions and synonomy shows that the Strix of the older authors is Strix stridula = S. aluco of Linnaeus, viz. the Tawny Owl, so that on the principle of Linnean tautonomy this will be the type” (BOU 1915); "Strix Linné, Syst. Nat., ed. 10, 1, 1758, p. 92. Type, by tautonymy, Strix stridula Linné (Strix, prebinomial specific name in synonymy) = Strix aluco Linné." (Peters 1940, IV, 156).  This is the third diagnosed genus in avian taxonomy. Linnaeus's Strix comprised eleven  species (S. Bubo, S. scandiaca, S. Asio, S. Otus, S. Scops, S. Aluco, S. funerea, S. Nyctea, S. stridula, S. Ulula, S. passerina). The hooting cries of the Tawny Owl are commemorated, sometimes fancifully, in literature and song.
