Hooded Merganser in October
Where hooded mergansers are in October, whether they are nesting, and the best foods to offer right now.
October in the Hooded Merganser's year
October brings the year's great turnover. The last long-distance migrants depart, winter visitors arrive from the North, and sparrows flood back into brushy edges and feeder yards. The first hard frosts end the insect season across most of the continent.
For the Hooded Merganser specifically, October is a fall month of relative routine, with the species settled into its seasonal pattern across its range. Across the 54 states and provinces where hooded mergansers occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.
Where hooded mergansers are in October
- Southern states
- absent
- Mid-latitudes
- year-round resident
- Northern states & Canada
- absent
In October, hooded mergansers 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 October
Hooded mergansers are not nesting in October. The season runs February–May at mid-latitudes.
That makes October 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.
What to feed in October
- Small fish in ice-free water
Nests in tree cavities and wood-duck-style boxes near quiet wooded ponds and slow rivers.
This is the month to get winter feeding stations established — birds are scouting the food sources they'll rely on all winter.
