Highlighted months are when evening grosbeaks are expected in Connecticut. 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 evening grosbeaks into Connecticut 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.
