Not being able to find the dead donkey story, a mainstream UK newspaper reported that:-
More than 20 dead foxes were killed and left to hang by their necks as a warning to others in Santa Cruz Province, Argentina by wildlife photographer Gabriel Rojo.
“I think an observer feels sorry for seeing so many dead animals, especially in times when wildlife is more value alive than dead with the large amount of tourists who like to see and observe wildlife around the world.”
Aw, grow up man and newspaper alike.
In the UK this is still called a gamekeeper’s gibbet.
Or, in my case, old school land owners were generally well pleased at my mole gibbets.
An example of a mole catchers gibbet.
It’s a common way of showing the land owner that the you are doing your job and, as a little bonus, the smell deterred other pests from trying it on.
Done for hundreds of years in a multitude of countries and by birds i.e.
Butcher birds are insect eaters for the most part, but will also feed on small lizards and other vertebrates. They get their name from their habit of impaling captured prey on a thorn, tree fork, or crevice. This “larder” is used to support the victim while it is being eaten, to store prey for later consumption, or to attract mates. (Wiki).
But was it limited to animals?
Nope, in medieval times people were suspended in iron frames or cages to die and rot down as a warning to others. Not nice at all.
