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.

As the Blue-series alleles are recessive, a bird must receive one of the blue-series alleles from each parent in order for the blue-series trait to be seen visually. A bird that has only one recessive gene for a specific trait is said to be "split" for that trait. Thus, a bird who receives a green base-color gene from one parent and a blue ...
