Common Grackles in Texas

Common Grackles live in Texas all year. Hard freezes are brief outside the Panhandle, so most feeder birds face heat and drought stress more than cold. That makes the cold months the time your yard matters most to them: their winter diet shifts toward waste grain and acorns.

Humid subtropical in the east and along the Gulf, semi-arid to arid in the west; long, hot summers and short, mild winters over most of the state.

Across Texas, grackles typically nest from March–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.

Afternoon highs regularly exceed 95°F — nest boxes need shade or light-colored, ventilated construction, and water matters as much as food.

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