The common grackle (Quiscalus quiscula)

The common grackle (Quiscalus quiscula) is a large icterid found in large numbers through much of North America. First described in 1758 by Carl Linnaeus, the common grackle has three subspecies.

Adult common grackles have a long and dark bill, pale yellow eyes, and a long tail. Adults often have an iridescent appearance on their head, especially males. Common grackles are found in much of North America east of the Rocky Mountains.
