In Montana, eastern kingbirds are present through the warm months, arriving around May and heading south again by August.

These windows are set by latitude: Montana sits in the middle 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.

Highlighted months are when eastern kingbirds are expected in Montana. 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 May 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.

Once nesting begins around June, adults switch to protein-rich food for their young and visits to feeders become quick and purposeful. Expect the busiest activity at dawn.

What eastern kingbirds eat while they're here

  • Bees, wasps and beetles

Kingbirds fearlessly chase hawks and crows; they perch on fences over open fields.
