I was about to ask about what is in the ear of the second bear, but then I read your previous skeet and now I assume it’s a tracker. Is that right?

That is the satellite tracker. However, if you look at the other bear you will see small tags in his ears. That’s a tag in case he gets recaptured. A lot of bears get caught, put in polar bear jail for a while and then released further up the coast for everyone’s safety.
