- April–September
In North Dakota, bluebirds are present through the warm months, arriving around April and heading south again by September.
These windows are set by latitude: North Dakota sits in the northern part of this species' range, so timing here runs later than the continental average — the season starts later this far north and the birds wait for it. In any given year, weather can move the first arrivals by a week or two either way.

Getting ready before they arrive
The week before April is the time to act. Have feeders cleaned, filled and out by early April — the first bluebirds into North Dakota are scouting for reliable food, and a station that's ready early gets added to their route.
Bluebirds 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. Eastern Bluebird 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 bluebirds eat while they're here
- Grasshoppers, crickets and beetles
- Caterpillars and spiders
Bluebirds hunt from perches over short grass. Put mealworm feeders in the open, near a low perch, and offer small amounts at the same time each day.
