Yellow-rumped Warbler in September
Where yellow-rumped warblers are in September, whether they are nesting, and the best foods to offer right now.
September in the Yellow-rumped Warbler'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 Yellow-rumped Warbler specifically, September is a fall month of relative routine, with the species settled into its seasonal pattern across its range. Across the 57 states and provinces where yellow-rumped warblers occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.
Where yellow-rumped warblers are in September
- Southern states
- absent
- Mid-latitudes
- year-round resident
- Northern states & Canada
- absent
In September, yellow-rumped warblers 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.
Nesting in September
Yellow-rumped warblers are not nesting in September. The season runs May–July at mid-latitudes.
Outside the nesting season, yellow-rumped warblers 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
- Caterpillars and flies
The warbler most likely at a winter feeder; suet and wax myrtle bring them in.
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.
