Scanned photo from my visit in July 2002.
Osnabrück, Hannover and some others once kept several bear species together. It began when the animals arrived as cubs and it was only supposed to be temporary. But then for various reasons they never built exhibits for each species; the bears grew up and got old together; so this went on. Only one Brown remained when I went to Hannover Zoo but Osnabrück still had one Polar, two Brown and one Asiatic Black.
