Little Red and Big Red

They were both here together at the same time today in the garden. Little red usually shows up in the late afternoon after the grey and black squirrels have gone. I wondering if this larger rusty colour squirrel might be related to the smaller red squirrel. They did not interact with each other or did not run the other off! Was nice to see them both at the same time. Hoping for warmer weather soon! Too cold to venture out there today!
