Hooded Merganser in March
Where hooded mergansers are in March, whether they are nesting, and the best foods to offer right now.
March in the Hooded Merganser's year
March is a month of transition. Winter visitors begin drifting north, the first spring migrants appear in the South, and resident birds are in full song. Weather swings hard — a warm week can push migration early, and a late blizzard can catch migrants short of food.
For the Hooded Merganser specifically, March is a spring month inside the nesting season — one of the most active and demanding periods of this bird's year. 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 March
- Southern states
- absent
- Mid-latitudes
- year-round resident
- Northern states & Canada
- absent
In March, 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 March
March is inside the Hooded Merganser nesting season. Nest: tree cavity or nest box near water. Clutch 6–18 eggs, incubation 26–41 days, 1 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 March
- Small fish in ice-free water
Nests in tree cavities and wood-duck-style boxes near quiet wooded ponds and slow rivers.
Migration brings new faces to feeders. Keep seed fresh and watch for birds passing through that you won't see again until fall.

Watching hooded mergansers this month
In March, 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 Hooded Merganser 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.
