Black-crowned Night Heron in March
Where black-crowned night herons are in March, whether they are nesting, and the best foods to offer right now.
March in the Black-crowned Night 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 Black-crowned Night 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 53 states and provinces where black-crowned night herons occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.
Where black-crowned night herons are in March
- Southern states
- absent
- Mid-latitudes
- year-round resident
- Northern states & Canada
- absent
In March, black-crowned night 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 Black-crowned Night Heron nesting season — about a month earlier in the South and a month later in the North. Nest: stick nest in trees or reeds, in colonies. Clutch 3–5 eggs, incubation 21–26 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.
What to feed in March
- Fish in ice-free water
Roosts in dense trees by day and raids ponds at night; often overlooked in city parks.
Migration brings new faces to feeders. Keep seed fresh and watch for birds passing through that you won't see again until fall.

Watching black-crowned night 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.
