Great Blue Heron in March
Where great blue herons are in March, whether they are nesting, and the best foods to offer right now.
March in the Great Blue Heron'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 Great Blue Heron 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 60 states and provinces where great blue herons occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.
Where great blue herons are in March
- Southern states
- absent
- Mid-latitudes
- year-round resident
- Northern states & Canada
- absent
In March, great blue herons 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 Great Blue Heron nesting season. Nest: stick platform high in trees, usually in colonies. Clutch 2–7 eggs, incubation 25–30 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
- Fish and any open-water prey
A regular at backyard ponds; net or decoy-protect ornamental fish if one moves in.
Migration brings new faces to feeders. Keep seed fresh and watch for birds passing through that you won't see again until fall.

Watching great blue herons 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.
