Black-capped Chickadees in Illinois

Black-capped Chickadees live in Illinois all year — northern two-thirds. Cold, windy winters in the north; the southern tip is milder and hosts more wintering species. That makes the cold months the time your yard matters most to them: their winter diet shifts toward cached seeds and insect eggs; suet and sunflower at feeders; poison-ivy and bayberry fruit.

Humid continental, grading from the Lake Michigan shore and prairie north to the forested Shawnee Hills in the south.

Across Illinois, black-capped chickadees typically nest from April–July. Nest site: excavates or reuses cavities in soft, rotting wood; readily uses nest boxes. Females lay 1–13 eggs (usually 6–8), incubate for 11–14 days, and young leave the nest after 12–16 days.

Hot, humid summers; much of the state is farmland, so backyard native plantings matter.

• Have boxes cleaned and mounted before March — black-capped chickadees begin prospecting ahead of egg-laying.
• Use a 1 1/8 in round entrance on a 4 × 4 in floor, mounted 5–15 ft.
• 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.
