Common Grackles in Ohio

Common Grackles live in Ohio all year. Snow and sub-freezing stretches are routine; Carolina Chickadees hold the south and Black-capped the north. That makes the cold months the time your yard matters most to them: their winter diet shifts toward waste grain and acorns.

Humid continental; cold winters and warm summers, with Lake Erie moderating the north coast.

Across Ohio, grackles typically nest from April–June. Nest site: bulky cup in dense conifers, often in loose colonies. Females lay 4–6 eggs, incubate for 13–14 days, and young leave the nest after 12–15 days.

Warm, humid summers; western Lake Erie marshes are a major migration stopover.

• Common Grackles don't use nest boxes. Keep dense native shrubs and trees such as white oak, bur oak for nest sites.
• Delay heavy pruning of shrubs until after June.
