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 pine grosbeaks 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.
