Hooded Merganser in May
Where hooded mergansers are in May, whether they are nesting, and the best foods to offer right now.
May in the Hooded Merganser's year
May is the peak of the birding year. Migration floods the North, dawn chorus is at its loudest, and nesting is underway across most of the continent. By month's end the first broods of the year are hatching in mid-latitudes.
For the Hooded Merganser specifically, May 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 May
- Southern states
- absent
- Mid-latitudes
- year-round resident
- Northern states & Canada
- absent
In May, 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 May
May is inside the Hooded Merganser nesting season — about a month earlier in the South and a month later in the North. Nest: tree cavity or nest box near water. Clutch 6–18 eggs, incubation 26–41 days, 1 per season.
The southern nesting season has already wound down, but northern pairs are still raising young — the whole season shifts later as you go north. 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 May
- Minnows, crayfish and aquatic insects
Nests in tree cavities and wood-duck-style boxes near quiet wooded ponds and slow rivers.
Adults feeding nestlings need easy calories. Some species that ignored feeders all winter now visit regularly, and you may see fledglings brought to feeders by their parents.

Watching hooded mergansers this month
In May, 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.
