Quiscalus Quiscula is a species of blackbird commonly found in North America. It is also known as the Common Grackle and can be identified by its striking iridescent black plumage and yellow eyes. While the bird's scientific name may not have any common synonyms, it does have several alternate names such as the Purple Grackle, Bronze Grackle, or Rusty Blackbird. Other blackbird species that may be confused with the Quiscalus Quiscula include the Red-winged Blackbird, Brewer's Blackbird, and Yellow-headed Blackbird. However, the Common Grackle can easily be distinguished by its longer tail and larger size.
