The Common Grackle (Quiscalus quiscula) is common in eastern North America, and since the 1970s has steadily spread west. It now breeds as far west as eastern British Columbia and central New Mexico, and records of vagrants elsewhere in the West have increased (Peer and Bollinger 1997, Jaramillo and Burke 1999). Northern populations are migratory, Great Lakes populations moving 1000 km on average (Dolbeer 1982). In this note, we document the first record of the Common Grackle for Sonora and summarize the status of the species in Mexico.
