In Wisconsin, winter wrens are a cold-season bird, arriving around September and heading back north to breed by April.
These windows are set by latitude: Wisconsin sits in the middle part of this species' range, so timing here tracks the continental average closely. In any given year, weather can move the first arrivals by a week or two either way.

Highlighted months are when winter wrens are expected in Wisconsin. 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 September is the time to act. Have feeders cleaned, filled and out by early September — the first winter wrens into Wisconsin 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.
