September in the Orange-crowned 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 Orange-crowned Warbler specifically, September is a fall month of relative routine, with the species settled into its seasonal pattern across its range. Across the 36 states and provinces where orange-crowned warblers occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.

What to feed in September
- Caterpillars, aphids, ants and spiders
One of few warblers that regularly visits winter feeders in the south and on the Pacific coast.
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.
