| Comment | Roger, Thank you for the prompt reply. What you say makes sense. What prompted my inquiry was the apparent suddenness of the cardinal's departure. The male's plumage makes him hard to miss, even if he isn't calling. The female somewhat less so, of course. The area where I have visited during the past four weeks (when I began to notice their absence) extends along the Mississippi River valley from just south of the Twin Tities, through western Wisconsin and northeastern Iowa. I have seen robins, in small migrating flocks, and occasionally larger flocks of red-wing blackbirds but few others of our exclusively summer winged friends. Local residents tell me they are accustomed to seeing cardinals visit their feeders during the winter. Winter temperatures typically fall below zero a dozen or more times during the winter months throughout this area, but I, like many songbirds, spend those chilly months far to the south.
