A very brave newcomer.
The only grey squirrel in the yard, that has been taken over by black squirrels.
Black and grey squirrels are the same species and can interbreed. A mutation in the gene that governs coat pigmentation is responsible for the black colouring.
The testosterone-fuelled black squirrels are faster, fitter, fiercely territorial and more aggressive, beating greys to food and mates.
His name...Stoney Braveheart
Good luck Stoney!
