● "54.  Tetrao, L.   141. urogallus, L.  (major, Br.  crassirostris, Brehm.  hybridus, L. cum Lyr. tetrice.  medius, Leisl.  intermedius, Langsd.  pseudourogallus, Brehm.  maculatus, Brehm.  urogalloides, Nilss.)   142. parvirostris, Bp.  (urogalloides, Middend.)" (Bonaparte 1856).  According to Mlíkovsky 2012, "the Black-billed Capercaillie should be called Tetrao urogalloides Middendorff, 1853, not Tetrao parvirostris Bonaparte, 1856." (syn.
