Chimney Swift in October
Where chimney swifts are in October, whether they are nesting, and the best foods to offer right now.
October in the Chimney Swift's year
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 Chimney Swift specifically, October is a fall month of relative routine, with the species settled into its seasonal pattern across its range. Across the 42 states and provinces where chimney swifts occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.

In October, chimney swifts are absent in the South, mostly absent (migration only) 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.
Nesting in October

Outside the nesting season, chimney swifts put their energy into feeding and flocking rather than territory and young — which is exactly what makes them easier to watch and attract this month.
What to feed in October
- Winters in the Amazon basin
Leave an uncapped masonry chimney open April–October, or build a swift tower; populations have fallen by roughly two-thirds since 1966.
This is the month to get winter feeding stations established — birds are scouting the food sources they'll rely on all winter.
