Crow mag's Barred Owls reminded me of my trip to northern Minnesota 2 winters ago. There was an irruption of owls, pushed south from Canada by a shortage of natural food, namely small rodents. Jack and I spent 3 days there. Each morning it was 40 degrees below when we left the motel in the dark. It never got above 20 below during the day. Being compassionate fellows, during a mid-day lull we drove 40 miles to a Petco store to buy some food for the owls. Coincidentally, this helped our photo efforts tremendously.
