Grackles are iridescent, long-tailed blackbirds common in North and South America, known for their loud, mechanical-sounding calls and intelligence. The three main U.S. species are the Common Grackle, Great-tailed Grackle, and Boat-tailed Grackle, all omnivorous foragers found in suburban lawns, fields, and marshes, often gathering in large flocks, especially in winter. Males are glossy black with bright yellow eyes, while females are duller brown, and they are known for being opportunistic eaters and clever problem-solvers.
