In Iowa, brown creepers are a cold-season bird, arriving around October and heading back north to breed by March.

Month by month in this state
Highlighted months are when brown creepers 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 October is the time to act. Have feeders cleaned, filled and out by early October — the first brown creepers into Iowa are scouting for reliable food, and a station that's ready early gets added to their route.
Through the winter, consistent food matters more than variety — birds map dependable stations into their daily routes and rely on them hardest during cold snaps.

- Overwintering insects; some suet
