Late autumn turns into early winter in the backyard. The change of the guard is complete. Long gone are the birds of summer; settled in are the birds of winter. Bird feeding gets busier with each passing cooler day. Especially in the the North, winter residents have adopted their routines for survival, starting each day with voracious early morning feedings to refuel the fat that was expended during longer, colder nights. Again in late afternoon, they feed heavily to fuel their furnaces for the long night ahead.
