Least Flycatcher in September
Where least flycatchers are in September, whether they are nesting, and the best foods to offer right now.
September in the Least Flycatcher's year
September is the peak of fall migration. Huge numbers of birds move south on cold fronts, mixed flocks form, and summer residents slip away almost unnoticed. Young birds making their first migration appear in places the species rarely visits.
For the Least Flycatcher specifically, September is a fall month of relative routine, with the species settled into its seasonal pattern across its range. Across the 41 states and provinces where least flycatchers occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.
Where least flycatchers are in September
- Southern states
- absent
- Mid-latitudes
- mostly absent (migration only)
- Northern states & Canada
- absent
In September, least flycatchers 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 September
Least flycatchers are not nesting in September. The season runs May–July at mid-latitudes.
Outside the nesting season, least flycatchers 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 September
- Midges, flies, ants, beetles and caterpillars
The most likely small 'empid' in eastern yards; identify it by voice, not plumage.
Migrants passing through may stop at feeders for a day and never return — September rewards watching closely. Natural seed and fruit crops are abundant, so feeder traffic can be uneven.
