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.
