Nesting in Idaho

Across Idaho, ash-throated flycatchers typically nest from April–July. Plan around that window: March for setup, July for clean-out.

Hot, dry summers in the Snake River Plain and cool mountain summers.

Have boxes cleaned and mounted before March — ash-throated flycatchers begin prospecting ahead of egg-laying.
