A wolf confirmed to have returned to Brittany after more than a century of absence was identified through genetic analysis rather than photographic evidence. The confirmation came from a swab taken from a bite wound on a dead sheep in Mellionnec and analyzed in a Belgian laboratory. This marked the first time a wolf in the region had been identified using DNA analysis, offering more certainty than visual identification alone. Since 2022, the presence of wolves in Finistère has been regularly documented by photographs and other evidence, with several attacks on flocks confirmed by the French Office for Biodiversity. Field monitoring is conducted by the Group Loup Bretagne, an associative collective formed of members of the Breton Mammal Group and Bretagne Vivante. The association identifies individual wolves through fur patterns, having identified at least seven different wolves in the past four years. The seventh wolf, named Quénec, was found to originate from the first pack of the Hautes-Fagnes in Belgium. Images of Quénec were posted on Facebook by a hunter on January 18, 2026, during a hunt in the forest of Quénécan in the commune of Saint-Brigitte. An hour later, the same animal was spotted in Silfiac, identifiable by its particular phenotype. The next day, a sheep was found dead, and another was discovered dead in Mellionnec, partially eaten. Olivier Le Cam, a veterinarian specializing in wolf monitoring in Brittany, performed swabs on bite wounds to collect DNA, which was sent to the GeCoLab laboratory in Liège for analysis. The results, released in May 2026, confirmed Quénec as a male born around 2021, belonging to the German-Polish lineage, originating from the first litter of the founding pair Akéla and Maxima. The wolf had never been re-genotyped on Belgian soil, indicating it left its native region without leaving any other scientific trace there. All the wolves identified in Brittany are young males in territorial dispersion, with no stable pack having settled in the region. The genetic analysis provided certainty that photo-identification alone cannot guarantee. Young males searching for a territory are the typical behavior of the species during the recolonization phase, traveling hundreds of kilometers. Nouzil, another wolf, was spotted in the Loiret in December 2024 and crossed Normandy, the Mayenne, and the Ille-et-Vilaine before reaching Cornouaille, covering more than 1,000 kilometers in a few months. In the Arrée Mountains, Loargann has been followed for longer than the others, but in June and July 2026, no images confirmed its presence, leading to concerns. The hypothesis was that successive heatwaves pushed wolves and prey to seek shelter away from usual photographic traps. Loargann reappeared in August 2026, with territorial marking observed on August 8 and the animal seen again on August 24. Two attacks on flocks occurred in the area during this time, but no formal link has been established between these predations and Loargann. The story highlights the fragility of visual evidence compared to the rigor of laboratory analysis.
