Thanks Terry! It's a good time of year for activity in the tiger enclosure particularly when no one else is there (which at Whipsnade has to be in Winter!). I've noticed (now he's on his own and the other tigers aren't there to stalk and muck about with), Czar will often spot you alone from across the enclosure and make his way with eyes on, weaving between the trees and the old platforms. There's sometimes something quite unnerving about him getting larger and larger in the lens!
