Do wolves eat bear meat?

The wiki implies boar meat is the best, and that they'll eat anything else except wolf meat. I have a wolf breeding pen, and I throw a lot of 'extra' raw meat in the pen to keep the breeding going full steam. I've only noticed wolves eating boar/deer meat. I've never gotten them to eat anything else, but am the most curious about bear meat. I have a ton extra, so thought it'd make a good surplus for feeding my wolves, but the stacks of bear meat remain untouched. Any better sources on what wolves eat than the wiki?
