According to ISIS0 1.1 is kept at Sofia Zoo and 0.0.1 is kept at Zoo Decin. Cologne keeps 0.2, so thats a total of five (1.3.1) and not four like I have written.
Hi Toddy, I correct a bit this information about Grizzly bears. There are at least further two Grizzly bears (1.1) are exhibited in Europe. This pair were lived at Budapest Zoo for many years until the past years, when they were removed to an other location in Hungary (after that they got down from the ISIS, I think it was happened approximately 1,5-2 years ago). This happened because Budapest Zoo currently renovate that part of the zoo where they lived. The zoo plan to keep an other bear species, so at present I don't know they return to the zoo or not.
