In Ohio, purple martins are present through the warm months, arriving around April and heading south again by August.

Highlighted months are when purple martins are expected in Ohio. The edges of the window are the interesting weeks — first arrivals and last departures vary most from year to year.
Getting ready before they arrive
The week before April is the time to act. This species doesn't use feeders much, but water and cover matter — a clean birdbath and undisturbed shrubs make a yard far more attractive to a newly arrived bird.
Purple martins nest in cavities, so boxes need to be up and cleaned before arrival — a box mounted after they've claimed territories will usually sit empty until next year. Purple Martin nest box dimensions and mounting →
Once nesting begins around May, adults switch to protein-rich food for their young and visits to feeders become quick and purposeful. Expect the busiest activity at dawn.
What purple martins eat while they're here
- Dragonflies, flies, beetles and moths
- Flying ants and wasps
Purple Martins do not use feeders. Supporting them means supplying correctly built colony housing in the open and managing House Sparrows and starlings.
