It’s not a simple answer! I don’t know. He only showed up for a fraction of a second before running off. The one thing that really identified the Male was that his tail was very short and busy. As he didn’t come into the shot fully, I can’t make out his tail. He has quite a thick coat which the Male certainly did.
However, as you can see from the photos, they are 2 different Foxes, the 2nd photo is the Vixen. These two shots were only 30 seconds apart too, so they were together, which is unusual for Foxes.
It’s too big to be one of the young, so I can only hope this is finally proof that the Male is around and well.
