In Montana, ash-throated flycatchers are present through the warm months, arriving around April and heading south again by August.
These windows are set by latitude: Montana 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 ash-throated flycatchers into Montana are scouting for reliable food, and a station that's ready early gets added to their route.
Ash-throated flycatchers 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. Ash-throated Flycatcher 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.
