For quite a while they stayed at some distance. I wasn't going to go chasing them. No way did I want to disturb them. So I kept my patience and hoped they'd come closer. I got a real treat.
Busted! Finally spotted me after nearly an hour of watching from afar. It came with 20 metres of me. Nearly too close for my camera lens.
One last look in fading light, as it moved away to hunt in a new area.
