The U.S. Fish and Wildlife Service notes that Yellowstone National Park officials report that intraspecific conflicts between wolf packs in August and September accounted for the deaths of 6 wolves from 5 different packs.
In addition, the number of pups in YNP declined in 2008. At least 2 packs (possibly as many as 4 packs) have no surviving pups this fall. The cause for lower pup survival is unknown, but investigations are ongoing, according to FWS.
