I remeber seeing the zoocheck report in polar bears in the UK, and this was maybe the mid-eighties, their animals reportedly showed the least stereotypic behaviour of all the polar bears at that point in the UK. I believe there was a male and two females at the time of the study, and one of the females may have been in the cubbing den. I don't have access to this study and this is purely from memory, so I can't remember which animals these were. I'm guessing the three were the last polar bears at Belfast, does anyone know if they bred/ where they went?
