Jailbreak?

It's been a while since I had the opportunity to take a walk along the perimeter fence of the Chodham Ranges near where I live. This evening I took advantage of the sunny evening and a reasonably early home time for a stroll.

The ranges are heavily fenced due to the use of live ammo, though they play host to a herd of deer who seem to come to no harm. Birds and other small creatures (I also saw a rabbit) are free to come and go, and I was delighted to catch this Robin in my camera sights.
