Northern Rough-winged Swallow in April

April is when spring migration hits its stride. Waves of migrants move north on warm southerly winds, wintering birds leave for good, and early nesters are already on eggs in the South. Every week brings species that weren't there the week before.

For the Northern Rough-winged Swallow specifically, April is a spring month inside the nesting season — one of the most active and demanding periods of this bird's year. Across the 55 states and provinces where northern rough-winged swallows occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.

In April, northern rough-winged swallows 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.

April is inside the Northern Rough-winged Swallow nesting season — about a month earlier in the South and a month later in the North. Nest: grass nest in a burrow, pipe or crevice near water. Clutch 4–8 eggs, incubation 12–16 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.

• Flies, midges, beetles and winged ants

Nests in drainpipes, culverts and bank holes rather than colonies; often the first swallow over a pond.

Migrants arriving after long flights are hungry — feeders can be genuine lifelines during cold, wet spells that suppress insects.

In April, 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.
