Mountain Chickadee in October

October brings the year's great turnover. The last long-distance migrants depart, winter visitors arrive from the North, and sparrows flood back into brushy edges and feeder yards. The first hard frosts end the insect season across most of the continent.

For the Mountain Chickadee specifically, October is a fall month of relative routine, with the species settled into its seasonal pattern across its range. 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.

Mid-latitudes

year-round resident

Northern states & Canada

absent

In October, 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.

Mountain chickadees are not nesting in October. The season runs May–July at mid-latitudes.

That makes October a useful month for nest-box work: cleaning out old nesting material, checking mounts and predator guards, and making repairs while boxes are empty. A box that's ready early gets claimed early.

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

This is the month to get winter feeding stations established — birds are scouting the food sources they'll rely on all winter.

Mountain chickadees are settled and predictable in October, which makes this a good month to learn the bird's routine — same feeders, same perches, same times of day.

If you have a Mountain Chickadee box up, this is the month to make sure it's clean, secure and ready — the box guide below has the exact hole size and mounting height this species needs.
