Getting ready before they arrive
The week before March is the time to act. Have feeders cleaned, filled and out by early March — the first ash-throated flycatchers into Oregon 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 April, adults switch to protein-rich food for their young and visits to feeders become quick and purposeful. Expect the busiest activity at dawn.
