When to expect mountain chickadees in British Columbia
Mountain Chickadees live in British Columbia all year. Mild, wet coastal winters where Anna's Hummingbirds now overwinter; cold interior winters. That makes the cold months the time your yard matters most to them: their winter diet shifts toward pine and fir seeds.
Temperate rainforest on the coast, dry interior valleys and mountains, and boreal forest in the northeast.
Nesting in British Columbia
Across British Columbia, mountain chickadees typically nest from June–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.
Dry, warm coastal summers; hot in the Okanagan.
- Have boxes cleaned and mounted before May — 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.
- Clean out old nests after each brood and again after July.
