Common Grackle (Quiscalus quiscula) - HBW 16, p. 778
French: Quiscale bronzé
Spanish: Zanate Común
Other common names: Florida Grackle (quiscula); Bronzed Grackle (versicolor); Purple Grackle (stonei)
Taxonomy: G.[racula] Quiscula Linnaeus, 1758, coast of South Carolina, USA.
According to DNA data, this species is ancestral to other members of genus. In the past, races versicolor and stonei were sometimes treated as two separate species. Further, these two races intergrade in E USA from Connecticut S to Louisiana; intermediate populations described as a distinct race, ridgwayi, but such treatment of this variable form unwarranted. Three subspecies recognized.

- versicolor Vieillot, 1819 - breeds in S Canada from E British Columbia E to S Quebec and Newfoundland, S in USA (E of Rocky Mts and W of Appalachians) to C Texas and W Mississippi; winters S to S Texas and E to South Carolina.
