OK, if you mean the window opposite June's Pavilion (which I'm sure you do) then the cub must have been moved, it spent most of its time at the other end of the enclosure.
Yes thats that is correct the one opposite June's Pavilion one of the staff members monitoring the cub told me that it had been moved there that morning for the first time. As you correctly said it had spent the majority of its time at the other end of the enclosure.
