September in the American Tree Sparrow'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 American Tree Sparrow specifically, September is a fall month of relative routine, with the species settled into its seasonal pattern across its range. Across the 50 states and provinces where American tree sparrows occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.
