Brown-headed Nuthatch in March

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 Brown-headed Nuthatch 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 14 states and provinces where brown-headed nuthatches occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.

In March, brown-headed nuthatches 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.

March is inside the Brown-headed Nuthatch nesting season — about a month earlier in the South and a month later in the North. Nest: excavated cavity in dead pine snags; nest boxes. Clutch 3–7 eggs, incubation 13–15 days, 1 per season.

In the South the season is already underway, while northern birds are still settling territories — a pair in Florida or Texas may be on eggs weeks before a pair in Minnesota or Ontario has even chosen a nest site. 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.

• Loblolly and longleaf pine seeds

Travels in family groups through pine woods; readily uses small nest boxes in pine yards.

Migration brings new faces to feeders. Keep seed fresh and watch for birds passing through that you won't see again until fall.

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 Brown-headed Nuthatch 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.
