Reporters found Mr Biggs, a self acclaimed "naturist", to be a woodsy story teller. This was the third time he had been attacked by a mountain lion. He had also survived a dangerous fall in the canyon. He told the folks at Animals and our Changing Planet that he was almost 100% sure that the mama bear knew him and wanted to save his life. He had mingled with bears in the past and had high-fived a yearling cub while its mother looked on.
NBC news, Paradise Post, and SFGate questioned the story, noting that the Department of Fish and Game was "unable to substantiate the attack".
The game warden who interviewed Biggs and looked at his wounds, concluded the injuries were inconsistent with those inflicted by mountain lions. Biggs's confiscated back pack was subjected to forensic analysis and no bear or lion DNA was found. The case was too weak to justify the Department's culling of a mountain lion.
Other Doubting Thomases came forth from the blogosphere, including a jolly Aussie (GrahamandFriends) who spoofed the story while donning a happy bear cap.
SF Gate's Tom Stienstra reported it "was the biggest hoax pulled off in years - or the wildlife story of the century."
To wrap this up, I decided to sample a few YouTube videos about mountain lion and bear encounters. This raised even more questions. I conclude there is no shortage of nature fakers to entertain the gullible.
