I'd be a little surprised if the panda keepers accompanying the pandas do not at least then returned with Amur tiger, Kira. It would be the most cost effective thing for them to do. A couple of keepers would be going with the pandas to help with their transition. While there they can get to know Kira as they slowly stop interacting with the pandas as the Calgary keepers assume full control. The keepers can then come back with her and she can begin her 30 day quarantine. They can keep her in the quarantine area until exhibit modifications are complete... which I doubt are much since it was designed for tigers to begin with. Once at least the indoor holding is ready they can transfer her there and bring Vasili in from Winnipeg if that's where he is. And when he is ready bring him over and let them both explore and get used to their yards prior to opening.
I think the biggest modifications will really be how you get into the exhibit and removing the gates at the end of the panda space. It would be nice if something else was put in there. Maybe a small Asian bird aviary. Just something else to look at.
Has anyone heard what they are looking to put in the panda education center?
