When to expect purple martins in Nebraska

Nesting in Nebraska
Across Nebraska, purple martins typically nest from May–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.
Hot summers with thunderstorms.
- Have boxes cleaned and mounted before April — 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.
