Great Blue Heron in September
Where great blue herons are in September, whether they are nesting, and the best foods to offer right now.
September in the Great Blue Heron'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 Great Blue Heron 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 great blue herons occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.

In September, great blue herons 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
Great blue herons are not nesting in September. The season runs February–June at mid-latitudes.
Outside the nesting season, great blue herons 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
- Fish, frogs, crayfish and voles
A regular at backyard ponds; net or decoy-protect ornamental fish if one moves in.
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.
