When to expect purple martins in Saskatchewan

Purple Martins are summer residents in Saskatchewan, arriving shortly before nesting begins in June and leaving after the young are independent. Through the season they feed on dragonflies, flies, beetles and moths; flying ants and wasps.

Continental — prairie in the south, boreal forest in the north.

Nesting in Saskatchewan

Across Saskatchewan, purple martins typically nest from June–July. Nest site: in the East, nests almost entirely in human-supplied martin houses and gourds. Females lay 3–6 eggs, incubate for 15–18 days, and young leave the nest after 26–32 days.

Warm, sunny summers.

  • Have boxes cleaned and mounted before May — purple martins begin prospecting ahead of egg-laying.
  • Use a 1 3/4–2 1/8 in round, or starling-resistant crescent (3 × 1 3/16 in) entrance on a 6 × 6 in minimum (6 × 12 in preferred) floor, mounted 10–20 ft on a telescoping pole, 40+ ft from trees.
  • Fit a pole baffle or hole guard; ventilation gaps and drainage holes are essential.
  • Clean out old nests after each brood and again after July.

Feeding purple martins through the Saskatchewan year

Purple Martins do not use feeders. Supporting them means supplying correctly built colony housing in the open and managing House Sparrows and starlings.

  • Best foods: Crushed eggshells (calcium) offered on a tray near housing.
  • Avoid: Seed and suet feeders — martins will not use them.
  • In Saskatchewan's summer: offer water and insect foods; natural food is abundant.
