Western Bluebird in May
Where western bluebirds are in May, whether they are nesting, and the best foods to offer right now.
May in the Western Bluebird'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 Western Bluebird 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 12 states and provinces where western bluebirds occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.
Where western bluebirds are in May
- Southern states
- absent
- Mid-latitudes
- year-round resident
- Northern states & Canada
- absent
In May, western bluebirds 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 Western Bluebird nesting season. Nest: cavity or nest box. Clutch 2–8 eggs, incubation 12–17 days, 1–2 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 May
- Beetles and grasshoppers
Uses 1 1/2 in nest boxes in open oak and pine woodland; boxes have helped recovery in the Pacific Northwest.
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 western bluebirds 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.
If you have a Western Bluebird box up, watch from a distance for comings and goings — steady traffic means an active nest — the box guide below has the exact hole size and mounting height this species needs.
