Research stag “Ossi” killed on Rügen: A shot against science

On the Baltic Sea island of Rügen, the radio-collared research stag “Ossi” was killed in September 2026.

According to the Rügen and Hiddensee Hunting Association, no shooting permit had been granted for the clearly marked animal.

The young red deer wore a conspicuous yellow collar transmitter with the number 60, as well as ear tags. As the first radio-collared young stag in the “Wild auf Wanderschaft” research project, he provided movement data on red deer on Rügen and Hiddensee over an extended period. The data was meant to help researchers understand how the animals move between forests, fields, coastal areas and tourist-frequented zones. With “Ossi”, one of the project's central research animals is now dead.

Clearly marked and yet killed

Thomas Nissen, chairman of the Rügen and Hiddensee Hunting Association, described the kill as a scientific and wildlife-ecological loss. The project had been well known on the islands, had been featured in the media several times, and had also been discussed at a red deer symposium. The association is calling for clarification, while at the same time pointing out that it is not an investigating authority.

The case raises a fundamental question: how reliable is the much-vaunted identification of wild animals before a shot is fired? A research stag with a yellow collar and ear tags should never have ended up in a kill statistic. Whether the markings were visible in the moment, under what conditions the shot was fired, and why the stag was killed at all, now needs to be clarified.

In Switzerland too, documented mis-kills repeatedly show the consequences of animals not being identified beyond doubt. Only in September 2026, in Avers in the canton of Grisons, a horse was mistaken for a red deer and shot dead, on the same hunting weekend during which two hobby hunters died in fatal accidents in Ticino. A case like that of “Ossi” therefore points not merely to individual failure, but to a structural risk of a hobby hunting practice in which flawed decisions end fatally for animals.

Outrage over the loss – but what kind of loss?

It is notable that it is precisely the hunting association publicly criticising the incident. Its communication focuses on the loss of scientific data, the wildlife-ecological damage, and the costs of a potential re-collaring. The fact that an individually known animal was killed, whose movements had been documented over an extended period, is thus treated above all as a loss for research and project funding.

For “Ossi” himself, this reckoning leaves little room. He was not merely a collar-wearer or a data set, but a living wild animal with his own range of movement and his own story. His fame protects him from being forgotten in hindsight, but it did not protect him from the shot.

It also remains unclear what happened to the animal after the kill. Public reports indicate that no information is currently available about the whereabouts of the game meat. Whether the stag was butchered, sold, passed on or eaten has not been documented.

What the case reveals about hobby hunting

“Ossi” was not an anonymous animal in a hunting statistic. He was a marked, scientifically monitored red deer. If even such an animal is not protected from an unlawful or unexplained kill, the question arises as to what practical significance markings, project communication and supposed duties of care actually have in everyday hobby hunting.

The red deer was declared Animal of the Year 2026 by the Deutsche Wildtier Stiftung. At the same time, across large parts of Europe it is still treated primarily as an object to be regulated by shooting. In Switzerland it was wiped out in the 19th century through intensive persecution and hunting, and only from the early 20th century onwards did it return across the Alps under its own power. The death of “Ossi” on Rügen shows how quickly scientific knowledge gain, individual animal welfare and the claim to careful hunting practice can be undone by a single shot.
