Prothonotary Warbler in March
Where prothonotary warblers are in March, whether they are nesting, and the best foods to offer right now.
March in the Prothonotary Warbler'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 Prothonotary Warbler specifically, March is a spring month of relative routine, with the species settled into its seasonal pattern across its range. Across the 26 states and provinces where prothonotary warblers occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.
Where prothonotary warblers are in March
- Southern states
- absent
- Mid-latitudes
- mostly absent (migration only)
- Northern states & Canada
- absent
In March, prothonotary warblers are absent in the South, mostly absent (migration only) 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
Prothonotary warblers are not nesting in March. The season runs April–June at mid-latitudes, starting roughly a month earlier in the South.
That makes March a useful month for nest-box work: cleaning out old nesting material, checking mounts and predator guards, and making repairs while boxes are empty. A box that's ready early gets claimed early.
What to feed in March
- Migrates to mangroves in the tropics
The only eastern warbler that nests in cavities — it readily takes small nest boxes over water.
Migration brings new faces to feeders. Keep seed fresh and watch for birds passing through that you won't see again until fall.
