In Iowa, eastern phoebes are present through the warm months, arriving around March and heading south again by August.

Highlighted months are when eastern phoebes are expected in Iowa. 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 March is the time to act. Have feeders cleaned, filled and out by early March — the first eastern phoebes into Iowa are scouting for reliable food, and a station that's ready early gets added to their route.
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.
