DEFINITIONS

HYPSIPETES
(Pycnonotidae; Ϯ Black Bulbul H. leucocephalus psaroides) Gr. ὑψιπετης hupsipetēs  high-flying, soaring  < πετομαι petomai  to fly; "Another interesting modification of form was exhibited among the Shrikes, in which the forked tail, acuminated wing, and short and feeble legs of the birds allied to Dicrurus appeared united to the head and bill of some of the Stares, particularly the genus Pastor.  Mr. Vigors characterized the form under the generic name of HYPSIPETES.   Rostrum subelongatum, debile, parum curvatum, apice leviter emarginatum; naribus basalibus, lateralibus, longitudinalibus, membrana partim clausis; rictus setis paucis, parum rigidis.   Alæ subelongatæ, subacuminatæ; remige prima brevi, secunda longiori septimæ æquali, tertia et sexta æqualibus, quarta et quinta æqualibus longissimis.  Pedes brevissimi, debiliores; acrotarsiis scutellatis.  Cauda subelongata, forficata, rectricibus extrorsum spectantibus.   HYPSIPETES PSAROÏDES."

● "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. Tetrao urogalloides).
