I'm going to assume that the honor will go to the PLAINS bison.  The WOOD bison that are at the wildlife conservation center in Portage and recently transferred to the lower Yukon River valley are not quite the same animal.  Wood bison are a northern bison.  The animals described in the article are the southern bison.  

This can confuse folks traveling up the Alaska Highway in the Yukon and then up near Delta Junction, to think these are the same bison, when they are not.  Folks thought the wood bison were extinct, so plains bison were brought up to Alaska in the 1930's.  It might be an interesting story for ADN to follow up on both the wood and plains bison found in Alaska, since it may be that many folks don't know there's a difference.
