North America - American Black Bear and American Bison

what's the story behind this photo? I could think of several captions...........

Not sure what you're refering to Astrobird. The keepers are spreading food. If you're wondering about the unusual animal mix, the black bears and bisons have been kept together for years. The bisons are far too big for the black bears to ever consider them as possible prey and the exhibit is very large. The same mix is at Safari Parc Peaugres.

I am far far more surprised that there are keepers in unprotected contact in the black bear exhibit than I am by the species mixture...
