Great Crested Flycatcher in August

August feels like summer but the year has turned. Southbound migration is quietly underway, many adults are molting into fresh plumage, and family groups are breaking up. Late nesters are still feeding young in the North while southern birds are already drifting toward wintering grounds.

For the Great Crested Flycatcher specifically, August is a summer month of relative routine, with the species settled into its seasonal pattern across its range. Across the 43 states and provinces where great crested flycatchers occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.

In August, great crested flycatchers are absent in the South, summer breeder 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.

Great crested flycatchers are not nesting in August. The season runs May–July at mid-latitudes, and up to a month later in the North.

That makes August a useful month for nest-box work: cleaning out old nesting material, checking mounts and predator guards, and making repairs while boxes are empty. A box that's ready early gets claimed early.
