Indigo Bunting in September

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 Indigo Bunting specifically, September is a fall month of relative routine, with the species settled into its seasonal pattern across its range. Across the 43 states and provinces where indigo buntings occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.

In September, indigo buntings 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.

Indigo buntings 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, indigo buntings 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.

Migrates at night by the stars; males sing from utility lines along brushy edges all summer.

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.
