The kodiak would probably die of strees, the 2 taronga had were sisters born in the states more than 30 years ago, making them extremely old by bear standards, and have a plague of age related health problems. they do not like chnage,especially these two.
When the male died, the electric fence was removed dwon the middle of the exhibit, to allow for more area, it took months just for one to cross over where the fence once was, and i beleive one bear never ever crossed to that side of the exhibit.
There would also now be no point in moving it. My guess would be sadley, the last remaining one will die within the next few months.
Mogo probably would not take the bear. it's not that easy saying- u take this bear we dont want it. Nor would mogo be appreciated as being a dumping ground for geriatic animals.
