Eastern Bluebirds in Texas

Eastern Bluebirds live in Texas all year — mainly the eastern two-thirds. 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 dogwood, sumac, holly, juniper and hackberry fruit; mealworms offered at feeders.

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, bluebirds typically nest from March–July. Nest site: secondary cavity nester — old woodpecker holes and nest boxes in open habitat. Females lay 2–7 eggs, incubate for 11–19 days, and young leave the nest after 15–20 days.

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

• Have boxes cleaned and mounted before February — bluebirds begin prospecting ahead of egg-laying.
• Use a 1 1/2 in round (1 9/16 in for Mountain/Western overlap) entrance on a 5 × 5 in floor, mounted 4–6 ft on a baffled pole.
• Fit a pole baffle or hole guard; ventilation gaps and drainage holes are essential.
• Clean out old nests after each brood and again after July.

Of the regional native plants we track for Texas, these 8 provide food or cover bluebirds use:

Bluebirds hunt from perches over short grass. Put mealworm feeders in the open, near a low perch, and offer small amounts at the same time each day.

• Best foods: Live or dried mealworms, Suet nuggets / insect-suet dough, Chopped native fruit.
• Avoid: Loose seed mixes — bluebirds rarely eat seed.
• In Texas's winter: Hard freezes are brief outside the Panhandle, so most feeder birds face heat and drought stress more than cold.
