When to expect mountain chickadees in Idaho
Mountain Chickadees live in Idaho all year. Cold winters with inversions in the valleys; mountain finches and Bohemian Waxwings move into towns. That makes the cold months the time your yard matters most to them: their winter diet shifts toward pine and fir seeds.
Semi-arid sagebrush plains along the Snake River and forested mountains to the north and center.
Nesting in Idaho
Across Idaho, mountain chickadees typically nest from May–July. Nest site: cavity or nest box lined with fur. Females lay 5–9 eggs, incubate for 14 days, and young leave the nest after 18–21 days.
Hot, dry summers in the Snake River Plain and cool mountain summers.
- Have boxes cleaned and mounted before April — mountain chickadees begin prospecting ahead of egg-laying.
- Use a 1 1/8 in 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.
