Why we don’t mind squirrels at our feeders: This red squirrel has claimed our feeder as his own, but thankfully his claims apply only to other red squirrels. When bumbling gray squirrels come too close, red shouts at them to go away, then scrambles to a defensive position, watching, his escape route assured. His spirit warms me no matter how cold it gets outside.

Gray squirrels seem frisky and energetic until you see one of these red squirrels run circles around them. Spitfire
is the word that comes to mind.
