RUBETRA
● (Muscicapidae; quasi-syn. Saxicola † Whinchat S. rubetra) Specific name Motacilla Rubetra Linnaeus, 1758; "The redstart's song considerably resembles that of the migrant furze-chat or "whinchat" of authors (saxicola-rubetra migratoria), consisting of short and rather plaintive detached staves" (Blyth 1836). The Richmond Card Index considers this name as a subgenus of Saxicola, but the text suggests to me a latinization of "the migrant furze-chat" rather than a nomenclatural statement.
● (Muscicapidae; syn. Saxicola † Common Stonechat S. torquatus rubicola) Late Med. L. rubetra small bird identified with the Stonechat by Gaza 1476 and Turner 1544; "BLACKCAP (Curruca atricapilla, Brisson). A variety of small black-headed birds are designated in different parts of Britain by the term Blackcap. The great titmouse (Parus fringillago), the marsh titmouse (P. palustris), the black-headed or reed bunting (Emberiza schœniclus), the stonechat (Rubetra rubicola), and even the black-headed gull, are all frequently called by this name" (Partington 1834); "Rubetra Partington, 1834, The British Cyclopaedia Nat. Hist, I, p. 506. Type, by monotypy, Rubetra rubicola Partington, 1834 = Motacilla rubicola Linnaeus, 1766." (JAJ 2021).
