The genus Sialia was introduced by the English naturalist William Swainson in 1827 with the eastern bluebird (Sialia sialis) as the type species. [2] [3] A molecular phylogenetic study using mitochondrial sequences published in 2005 found that Sialia, Myadestes (solitaires) and Neocossyphus (African ant-thrushes) formed a basal clade in the family Turdidae.
Many birds in other families are also commonly called "finches". These groups include the estrildid finches ( Estrildidae ) of the Old World tropics and Australia ; some members of the Old World bunting family ( Emberizidae ) and the New World sparrow family ( Passerellidae ); and the Darwin's finches of the Galapagos islands, now considered ...
