The Reds vs The Grays/Blacks So in my yard there are a few black squirrels who make permenant residence here. Every now and then a few gray ones come along. Then sometimes red squirrels come too. When Red is here it goes to all out war. Red attacks everyone. Scares the other squirrels and the birds! Then when the bigger black squirrels fight back Red bolts off as fast as his legs can carry him.
