Great-tailed Grackle
Quiscalus mexicanusAlso known as Mexican Grackle, Cuervo, Chango
Great-tailed grackles are boisterous, highly intelligent blackbirds renowned for their dramatic courtship displays and vast urban roosts. Males posture on exposed perches with puffed feathers, pointed bills, and widely flared keel-shaped tails while whistling a loud array of mechanical squeaks, pops, and chatter. Exceptionally adaptable, they have rapidly expanded their range north and west by thriving in farmland, city parks, and suburban parking lots.
