Sturnidae

Starlings are small to medium-sized birds that have a cosmopolitan distribution. Hybridization has been recorded in a few genera, Mino, Sturnus and Lamprotornis.

Acridotheres

A genomic study found signatures of ancient introgression between the Javan Myna (A. javanicus) and a subspecies of the Black-winged Myna (A. melanopterus tertius). This introgression event might have transferred genomic regions involved in black plumage color, but this hypothesis remains to be tested (Sadanandan et al., 2020).

Sturnus

Common Starling (S. vulgaris) and Spotless Starling (S. unicolor) are known to interbreed (Motis, 1992). Based on allozymes, the gene flow between these species was estimated at six migrants per generation (delaCruzCardiel et al., 1997).
