FWIW, I know this is so two weeks ago, but I found this blogpost which seems to add context that IG photo of Anthony Bourdain.
“There he was walked up into the hills, loaned an expensive rifle and pointed at a majestic stag. He dutifully shot the beast and was escorted down to the corpse where his keepers painted his face with the animal's arterial blood in a ceremony that once had an animistic meaning but now has none.”
