Where warbling vireos are in September, whether they are nesting, and the best foods to offer right now.
September in the Warbling Vireo'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 Warbling Vireo specifically, September is a fall month of relative routine, with the species settled into its seasonal pattern across its range. Across the 60 states and provinces where warbling vireos occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.

Nesting in September

Outside the nesting season, warbling vireos 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, beetles, bugs and wasps
A shade-tree bird of parks and streamside cottonwoods; sings from high in the canopy.
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.
