Blue Grosbeak in September
Where blue grosbeaks are in September, whether they are nesting, and the best foods to offer right now.
September in the Blue Grosbeak'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 Blue Grosbeak specifically, September is a fall month of relative routine, with the species settled into its seasonal pattern across its range. Across the 31 states and provinces where blue grosbeaks occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.
Where blue grosbeaks are in September
- Southern states
- absent
- Mid-latitudes
- mostly absent (migration only)
- Northern states & Canada
- absent
In September, blue grosbeaks 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
Blue grosbeaks are not nesting in September. The season runs May–August at mid-latitudes, and up to a month later in the North.
Outside the nesting season, blue grosbeaks 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
- Grasshoppers, crickets, caterpillars and beetles
Takes seed at low platforms and ground feeders near hedgerows; twitches its tail sideways as it perches.
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.
