Osprey 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 Osprey 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 61 states and provinces where ospreys occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.

In March, ospreys 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 Osprey nesting season — about a month earlier in the South and a month later in the North. Nest: huge stick nest on a pole, platform, snag or channel marker. Clutch 1–4 eggs, incubation 36–42 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.

Nests on poles, channel markers and purpose-built platforms; a platform near open water is often used.

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.
