When to expect tree swallows in Quebec

Tree Swallows are summer residents in Quebec, arriving shortly before nesting begins in June and leaving after the young are independent. Through the season they feed on flies, mayflies and dragonflies.

Humid continental in the St. Lawrence valley, boreal forest to the north, tundra in Nunavik.

Nesting in Quebec

Across Quebec, tree swallows typically nest from June. Nest site: nest box or tree cavity lined with feathers. Females lay 4–7 eggs, incubate for 11–20 days, and young leave the nest after 15–25 days.

Warm, humid summers in the south.

Have boxes cleaned and mounted before May — tree swallows begin prospecting ahead of egg-laying.
Use a 1 1/2 in entrance on a 5 × 5 in floor, mounted 5–10 ft.
Fit a pole baffle or hole guard; ventilation gaps and drainage holes are essential.
Clean out old nests after each brood and again after June.
