I had the good fortune of hunting in Germany and Austria for five years in the late seventies. Hunting and the ability to own a firearm are very hard-earned privileges in Europe. Because of that and hundreds of years of tradition, the European hunter is generally far more respectful of the game animal than the typical American. There is no concept of either hunting or firearm ownership as a "right".
For instance, in Europe, a last tribute is blown on the hunting horns for each species taken on a drive hunt. When I took my first red stag way back in 1976, my forester/guide stood on the side of the mountain at last light in the Franconian Jura and played the tribute for the stag. Beautiful. Hard to imagine a Colorado elk guide doing something similar.
The "last bite" as it is called is an almost universal tradition for big game. The second bit of branch goes in the hunter's hat.
Almost never in Europe and rarely in Africa will you see a European hunter in Camo. That is pretty much an American thing. And for most hunting I do (Turkey, Ducks, and geese are the exception), it is absolutely unnecessary.
In Namibia, there are very nearly as many Outfitters and PHs of German descent as Boer (Dutch) - Namibia was a former German colony (German Southwest Africa). Quite a few German hunters travel there, and videos of those hunts will show PH and hunter following those traditions.
There are a host of others. Germanic hunters normally carry a rifle slung under the left arm, with the muzzle forward and up, held by the left hand. Just as effective as the American over shoulder sling and the muzzle is always in total control. Game is gutted in a prescribed fashion. There are special names for game animals only used in the "hunters' language." And of course, the whole notion of selective shooting practiced on whitetail ranches today, has been the norm in most of Europe for nearly two centuries.
