Mountain Chickadees in Yukon

Mountain Chickadees live in Yukon all year. Long, dark winters well below −20°F. That makes the cold months the time your yard matters most to them: their winter diet shifts toward pine and fir seeds.

Subarctic continental with mountains, boreal forest and Arctic tundra in the north.

Across Yukon, 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.

Short summers with nearly 24-hour daylight.

• 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.
