Certainly she will bring her young now,this gray tried to horn in on the PB,I could not believe the speed and ferocity that little thing had,chased that gray OUT.
We only have Fox and grey squirrels here. They don’t get along very well. The smaller greys seem to be more aggressive. The foxes tend to avoid them. We also occasionally have hybrid fox-greys. This one has body color of a grey with a fox colored tail.
