Barn Owl in September
Where barn owls are in September, whether they are nesting, and the best foods to offer right now.
September in the Barn Owl'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 Barn Owl specifically, September is a fall month inside the nesting season — one of the most active and demanding periods of this bird's year. Across the 31 states and provinces where barn owls occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.
Where barn owls are in September
- Southern states
- absent
- Mid-latitudes
- year-round resident
- Northern states & Canada
- absent
In September, barn owls 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
September is inside the Barn Owl nesting season. Nest: barn lofts, silos, tree cavities and large nest boxes. Clutch 2–18 eggs, incubation 29–34 days, 1–3 per season.
The season is broadly synchronized across the range this month. During the nesting months, adults switch to protein-rich foods for their young, become more secretive around the nest site, and often visit feeders in quick, purposeful trips rather than lingering.
What to feed in September
- Voles, mice, rats and shrews
The best rodent control a farm can have; a single family takes thousands of voles a year.
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.
Watching barn owls this month
In September, the best watching is around food rather than the nest — adults make repeated foraging trips and are most visible at dawn and dusk. Give nesting birds space: if a bird is carrying food or scolding you persistently, you're close to a nest and should back off.
If you have a Barn Owl box up, watch from a distance for comings and goings — steady traffic means an active nest — the box guide below has the exact hole size and mounting height this species needs.
