Common Grackle in September
Where grackles are in September, whether they are nesting, and the best foods to offer right now.
September in the Common Grackle'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 Common Grackle specifically, September is a fall month of relative routine, with the species settled into its seasonal pattern across its range. Across the 50 states and provinces where grackles occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.
Where grackles are in September
- Southern states
- absent
- Mid-latitudes
- year-round resident
- Northern states & Canada
- absent
In September, grackles 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
Grackles are not nesting in September. The season runs April–June at mid-latitudes.
Outside the nesting season, grackles 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
- Beetles, grasshoppers and earthworms
Grackles arrive in flocks and can dominate open feeders; weight-activated and caged feeders help keep smaller birds fed.
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.
