DEFINITIONS

SETOPHAGA
(Parulidae; Ϯ American Redstart S. ruticilla) Gr. σης sēs, σητος sētos  moth; -φαγος -phagos  -eating  < φαγειν phagein  to eat; "G. SETOPHAGA.  Sw. in Zool. Journ. No. 10.    17. Setophaga ruticilla.  Muscicapa ruticilla, Lin. mas.  M. flavicaudæ. Gm. fem. Maritime parts.   18. Setophaga miniata.  Cinereous, breast and body beneath vermilion; tail black, the lateral tail feathers partly white.  Table land: woods of Valadolid; rare, size of the last.   19. Setophaga rubra.  Entirely red, ear feathers of a silky whiteness. Inhabits the same woods, and is of the same size as the last." (Swainson 1827 (May)); "SETOPHAGA.  Rostrum parvum; culmine carinato. Alæ mediocres; remigibus 1^ma et 4^ta æqualibus, 2^da et 3^tia æqualibus, longissimis. Cauda sub-elongata, rotundata. Pedes graciles, tarsis squamis anterioribus divisis, lateralibus integris.  ...  Type. Muscicapa ruticilla. Linn.  ...  It represents, in the new world, the Australian genus Rhipidura" (Swainson 1827 (July)); "Setophaga Swainson, 1827 (May), Philos. Mag., new ser., 1, fasc. 5, p. 368. Type, by subsequent designation (Swainson, 1827 (July), Zool. Journ., 3, p. 360), Motacilla ruticilla Linnaeus." (Lowery & Monroe in Peters 1968, XIV, 33). Doubtless time will soften the dismay of birdwatchers caused by the absorption of Dendroica, Parula and Wilsonia into Setophaga.
