Sixteen Norwegian Western Capercaillies in the Vosges: A Failed Second Chance

At first light, in a clearing in the Vosges, the silence can feel almost overwhelming. Yet, a few decades ago, sixteen western capercaillies from Norway arrived on these wooded slopes, following a delicate capture and journey intended to give the species a second chance. The birds were released in the hope that their imposing shapes would once again move through the bilberry bushes and fir trees. Two years later, the outcome was stark: almost none remained. Behind that tiny figure lies a far broader story - one showing that nature cannot be restored simply by placing animals in a forest. It also demands that we view the Vosges differently.

Sixteen Norwegian birds in a mountain landscape already transformed

The western capercaillie, also known as the wood grouse, is not inconspicuous by chance. It requires extensive, peaceful woodland, clearings rich in vegetation, bilberries, sheltered areas and, above all, long periods without disturbance. In the Vosges, the return of this emblematic species has long been a dream for naturalists, since its image remains closely linked with ancient, dense and wild forest. The sixteen birds caught in Norway were released in that spirit, on the assumption that the Vosges landscape could still accommodate them.

On paper, the project appeared logical: Norway still supported western capercaillie populations, while the Vosges contained forested massifs that resembled, at least in part, their original habitat. But a bird does not read maps. Monitoring of the released individuals soon revealed a less reassuring reality: after two years, nearly all had vanished, potentially through predation, accidents, disturbance or difficulties adapting to their new surroundings.

This initial failure was far from insignificant. It demonstrates that reintroduction is not a matter of moving a species from point A to point B, as though shifting a piece of furniture around a living room. The Norwegian western capercaillies arrived in mountains already heavily affected by forest roads, human activities, tourist visits and fragmented habitats. A forest may look untouched to us while no longer being suitable at all for such a demanding animal.

Why releases alone cannot save the western capercaillie

The first practical measure is to protect the site before attempting to return the animal to it. For the western capercaillie, this means genuinely respected quiet zones, forestry work adjusted to sensitive periods, and areas where dogs are kept away. Land managers now understand that the survival of a released bird depends as much on the quality of its habitat as on its ability to avoid danger during its first few weeks.

A common mistake is to believe that a high-profile release resolves a long-standing problem. We all recognise the appeal of a visible solution seeming more reassuring than slow, discreet work: planting a few trees, releasing a few animals or opening an initiative. Let us be honest: few people consistently monitor a sensitive area, avoid a closed path or accept that a mountain massif cannot be accessed at every hour. Yet these actions matter more than images of birds taking flight.

The western capercaillie also faces a chain of pressures that accumulate, sometimes unnoticed: an opened track, a mountain bike cutting through woodland, a dog running free, poorly timed forestry work or less favourable winters.

“Reintroducing a species without restoring the conditions it needs to be present is asking it to survive in a setting that is no longer its own.”

• Protect quiet areas during breeding and wintering periods;
• maintain a forest mosaic of clearings, understorey and bilberry bushes;
• reduce disturbance in the most vulnerable areas;
• monitor the birds over several years instead of judging the project after a single release.

In the Vosges, the fate of the western capercaillie goes beyond sixteen birds

This Norwegian episode has particular resonance because it concerns a visible, almost cruel failure, even though its causes are often diffuse. A western capercaillie does not always disappear in front of a walker. It may move away, be taken by a predator, fail to find sufficient food, abandon an overvisited area or never manage to breed. In the end, all that remains is one line in a report: sixteen released, almost none left two years later.

Later programmes in the Vosges helped refine understanding, without removing the underlying difficulties. Radio tracking, field observations and counts produced a clearer picture of what the bird needs. They also confirmed an uncomfortable truth: the western capercaillie is a thermometer of forest health. Where it still persists, conditions are often sufficiently balanced; where it declines, several vulnerabilities overlap.

The issue, then, is not confined to birdwatching enthusiasts. It concerns how the mountains are used, how timber is produced, how tourism is developed and how limited space is shared between human activities and wildlife. In the Vosges, some areas are already subject to seasonal restrictions or visitor guidance. These measures may be frustrating at the time, but they represent a straightforward choice: allowing certain species the chance not to be disturbed everywhere, all the time.
