Mountain Bluebird in July

July is the quietest month for bird song but one of the busiest for bird life. Many species are on second broods, young birds from first broods are independent, and natural food — insects, ripening fruit and seeds — is abundant. In the far South the first southbound shorebirds are already moving.

For the Mountain Bluebird specifically, July is a summer month inside the nesting season — one of the most active and demanding periods of this bird's year. Across the 23 states and provinces where mountain bluebirds occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.

In July, mountain 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.

July is inside the Mountain Bluebird nesting season — about a month earlier in the South and a month later in the North. Nest: cavity or nest box. Clutch 4–8 eggs, incubation 13–14 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.

Nests at high elevations in open country; takes nest boxes on fence lines.

Feeder traffic often dips as natural food peaks, but water becomes the big draw — a clean birdbath outpulls seed in hot weather.

In July, 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 Mountain 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.
