Prothonotary Warbler in June
Where prothonotary warblers are in June, whether they are nesting, and the best foods to offer right now.
June in the Prothonotary Warbler's year
June is the height of the nesting season. Most resident and migrant species are raising young, migration is essentially over, and bird activity peaks at dawn. By late June the first fledglings of the year are everywhere — clumsy, loud, and constantly begging.
For the Prothonotary Warbler specifically, June is a summer month inside the nesting season — one of the most active and demanding periods of this bird's year. 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 June
- Southern states
- absent
- Mid-latitudes
- summer breeder
- Northern states & Canada
- absent
In June, prothonotary warblers are absent in the South, summer breeder 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 June
June is inside the Prothonotary Warbler nesting season — about a month earlier in the South and a month later in the North. Nest: tree cavity or nest box standing in or over water. Clutch 3–7 eggs, incubation 12–14 days, 1–2 per season.
The southern nesting season has already wound down, but northern pairs are still raising young — the whole season shifts later as you go north. 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 June
- Caterpillars, beetles, mayflies and snails
The only eastern warbler that nests in cavities — it readily takes small nest boxes over water.
Expect to see adults carrying food away rather than eating it — they're feeding nestlings. Fledglings visiting feeders with their parents are a June highlight.

Watching prothonotary warblers this month
In June, 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 Prothonotary Warbler 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.
