Chimney Swift timing in Louisiana

- Status here
- Summer breeder
- Nesting season
- April–July
- Present roughly
- March–August
In Louisiana, chimney swifts are present through the warm months, arriving around March and heading south again by August.
These windows are set by latitude: Louisiana sits in the southern part of this species' range, so timing here runs earlier than the continental average — spring comes sooner, and the birds follow it. In any given year, weather can move the first arrivals by a week or two either way.
Month by month in this state
Highlighted months are when chimney swifts are expected in Louisiana. The edges of the window are the interesting weeks — first arrivals and last departures vary most from year to year.
Getting ready before they arrive
The week before March is the time to act. This species doesn't use feeders much, but water and cover matter — a clean birdbath and undisturbed shrubs make a yard far more attractive to a newly arrived bird.
Once nesting begins around April, adults switch to protein-rich food for their young and visits to feeders become quick and purposeful. Expect the busiest activity at dawn.
What chimney swifts eat while they're here
- Flies, beetles, ants and aphids in flight
Leave an uncapped masonry chimney open April–October, or build a swift tower; populations have fallen by roughly two-thirds since 1966.
