Mountain Chickadee in June

June is the height of the nesting season. Most resident and migrant species are raising young, migration is essentially over, and bird activity peaks at dawn. By late June the first fledglings of the year are everywhere — clumsy, loud, and constantly begging.

For the Mountain Chickadee specifically, June is a summer month inside the nesting season — one of the most active and demanding periods of this bird's year. Across the 15 states and provinces where mountain chickadees occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.

In June, mountain chickadees are absent in the South, year-round resident across the mid-latitudes, and absent in the northern states and Canada. That north–south split is the defining feature of this month: where you live changes which version of this bird you're looking at.

June is inside the Mountain Chickadee nesting season. Nest: cavity or nest box lined with fur. Clutch 5–9 eggs, incubation 14 days, 1–2 per season.

The season is broadly synchronized across the range this month. During the nesting months, adults switch to protein-rich foods for their young, become more secretive around the nest site, and often visit feeders in quick, purposeful trips rather than lingering.

Mountain Chickadees drop to lower-elevation towns in winter and readily use nest boxes.

Expect to see adults carrying food away rather than eating it — they're feeding nestlings. Fledglings visiting feeders with their parents are a June highlight.

In June, the best watching is around food rather than the nest — adults make repeated foraging trips and are most visible at dawn and dusk. Give nesting birds space: if a bird is carrying food or scolding you persistently, you're close to a nest and should back off.

If you have a Mountain Chickadee box up, watch from a distance for comings and goings — steady traffic means an active nest — the box guide below has the exact hole size and mounting height this species needs.
