Wilson i. pl. 3. f. 3.  Common on the Table land at Real del Monte and other places. I have some doubts whether this is not a distinct species: my specimen is of a young bird." (Swainson 1827, Philos. Mag., new ser., I (May)); "SIALIA.   ...   Bill short, the base depressed, the sides compressed, culmen slightly elevated: nostrils partly hid by setaceous feathers: mouth wide, and slightly bearded" (Swainson 1827, Zool. Journ., III (September)); "Sialia Swainson, 1827, Phil. Mag., n.s., 1 (5), p. 369. Type, by monotypy [and virtual tautonymy], Sialia azurea Swainson = Motacilla sialis Linnaeus." (Ripley in Peters 1964, X, 83). Although famed in song and literature, the Eastern Bluebird is a declining bird of eastern North America.

Sialis
(Turdidae; syn. Sialia † Eastern Bluebird S. sialis) Gr. σιαλις sialis, σιαλιδος sialidos  unidentified bird, so-called from its cry; "Ces deux circonstances ayant également lieu chez le Rouge-gorge bleu de l'Amérique septentrionale (Sylvia sialis), et s'y trouvant réunies à d'autres caractères de forme et d'habitudes qui avaient engagé Vieillot à en faire un Motteux, sous le nom de Ænanthe sialis, j'ai pensé que ce nouveau genres Sialis (Sialia des Anglais) devait également figurer dans ma cinquième famille.  Wilson et Vieillot disent positivement que l'espèce type, Sylvia sialis, niche dans des arbres creux et y pond des œufs d'un bleu pâle." (de La Fresnaye 1839); "Sialis (not of Latreille, 1803) Lafresnaye, Rev. Zool., 2, p. 162, 1839— type, by monotypy, Motacilla sialis Linnaeus." (Hellmayr, 1934, Cat. Birds Americas, Pt.
