DEFINITIONS

TETRASTES
(Phasianidae; Ϯ Hazel Grouse T. bonasia) Genus Tetrao Linnaeus, 1758, grouse (cf. Gr. τετρας tetras  bird mentioned by Symmachus, variant or error for τετραξ tetrax, τετραγος tetragos); Gr. -αστης -astēs  agent; "GEN. 82.  TETRASTES.  277. T. BONASIA L. — Tetrao Bonasia L. S. XII. p. 275. n. 9. — Lagopus Bonasia Klein Prodr. Av. p. 116. n. 3. — Haselhuhn.  In den Waldungen der nördlichen und gebirgigen Gegenden Europa's und Sibiriens bis jenseits der Lena.  ...  Der Lauf in der obern Hälfte befiedert, in der untern nackt, und vorn mit 2 vertikalen Schilderreihen besetzt; Zehen mit umfassenden Tafeln; der Schwanz 16federig, abgerundet." (Keyserling & Blasius 1840); "Tetrastes Keyserling and Blasius, Wirbelth. Eur., 1840, p. lxiv, 109, 299. Type, by monotypy, Tetrao bonasia Linné." (Peters, 1934, II, p. 37).

bonasia
● Olson in Ripley 1977, wrote of the extinct Red Rail, “Here bonasia is evidently intended to refer to Tetrastes bonasia, the Eurasian Hazel Hen, since in early accounts the Mauritian rail was referred to by vernacular names [e.g. “Gellinote”] elsewhere applied to the grouse. The derivation of bonasia itself is uncertain and more than one interpretation has been offered, both for this word and for Bonasa...The most common explanation is that these words are derived from Greek bonasos, Latin bonasus (a bull) ...Choate (1973) has proposed that Bonasa may be derived from Latin bonum (good) and assum (a roast). Mr Farrand offers two additional suggestions. The first is that the original authors did intend an allusion to Greek bonasos, but that they meant to suggest the birds’ timidity, since the Greek word refers specifically to a mythical bull... whose horns were unfit for fighting and thus was obliged to save itself by fleeing ignominiously. Conversely, he suggests the possibility that the allusion may be to the well-known tameness of certain grouse, the words Bonasa and bonasia being latinized forms of French bonasse (simple-minded or good-natured)” (‡Aphanapteryx).
