Yellow-rumped Warbler in May
Where yellow-rumped warblers are in May, whether they are nesting, and the best foods to offer right now.
May in the Yellow-rumped Warbler's year
May is the peak of the birding year. Migration floods the North, dawn chorus is at its loudest, and nesting is underway across most of the continent. By month's end the first broods of the year are hatching in mid-latitudes.
For the Yellow-rumped Warbler specifically, May is a spring month inside the nesting season — one of the most active and demanding periods of this bird's year. Across the 57 states and provinces where yellow-rumped warblers occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.
Where yellow-rumped warblers are in May
- Southern states
- absent
- Mid-latitudes
- year-round resident
- Northern states & Canada
- absent
In May, yellow-rumped warblers 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 May
May is inside the Yellow-rumped Warbler nesting season — about a month earlier in the South and a month later in the North. Nest: cup on a horizontal conifer branch. Clutch 1–6 eggs, incubation 12–13 days, 1–2 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 May
- Caterpillars and flies
The warbler most likely at a winter feeder; suet and wax myrtle bring them in.
Adults feeding nestlings need easy calories. Some species that ignored feeders all winter now visit regularly, and you may see fledglings brought to feeders by their parents.

Watching yellow-rumped warblers this month
In May, 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.
The state guides below show exactly where in your region yellow-rumped warblers are expected this month and which native plants hold them in a yard.
