The capercaillie – or Tetrao urogallus – was a common breeding bird throughout most of our history. Essentially a relic from the Ice Age, it was common in our early pine forests throughout the Stone and Bronze Ages. However, it clearly became less common during the Iron and Middle Ages, when widespread deforestation and heath formation took place. In Eastern and Central Europe, as well as the Alps, Appenines, and other mountainous areas, the capercaillie was a luxury item avidly hunted by the elite. Cooked like any game bird with onions, apples, berries, wild mushrooms and roots, wine, and honey would be added to the spiced sauce. According to the Irish Vikings, it tasted good with mead. Together with gannets, storks, herons, sparrowhawks, grey partridges, pheasants, and cranes, the capercaillie would grace the tables in the lord’s hall.

The capercaillie is a true giant. The male bird can reach up to 100 cm and weigh 6 kg, while the females only reach 2.5 kg; about the size of a goose and a small duck. The most exciting thing about the capercaillies is, of course, the males’ plumage. With a green breast, brown wings, and white spots on its spread-out tail, it’s easily recognizable by its dance and its marvelous cackling and croaking call. While its closest relative, the black grouse, prefers heaths and boggy areas, capercaillies are fond of pine forests with bogs and older pine woods. However, these forests should ideally be grazed by large ungulates to create the varied and open landscapes providing both shelter and open “ballrooms,” as biologists tell us (Ludwig 2023).

The Bavarian Alps and The Schwarzwald are home to the last remaining metapopulations of Capercaillies in Germany.

In a new study, long-term data from the Bavarian Alps was brought together to answer the primary question about the long-term trend development of the Capercaillie population in the Alps. More precisely, the scientists evaluated spring censuses from a total of seventy courtship sites from the Werdenfelser Land, the central Mangfallgebirge, and the transition between the eastern Mangfallgebirge and the western Chiemgau Alps over almost 40 years. The average trend across the three areas studied corresponded to a significant annual decline of 1.86%, or 60% for the whole period. For the first 25 years, the dwindling numbers were gradual. After 2010, however, a continuous annual decline of 6.57% set in. The results coincide with many deserted courtship areas. These results correspond to continuing declines in Capercaillie ranges elsewhere. Although the capercaillie is not redlisted worldwide, it is a fine barometer of the combined stress induced by climate and outdoor tourism.

According to Ludwig and his group of researchers, silvicultural changes associated with rising temperatures are the primary cause, but also strongly increasing recreational pressure on the last Capercaillie refuges is likely related to the observed trends. In Bavarian research, the impact of “off-piste” winter sports is mentioned. Also, the public support of these sports, augmented by websites marking our off-piste trails, seems to have pushed the consumption of the wilderness to new heights. Despite prohibitions against people staying overnight as well as e-mountain biking, which are deemed to disturb the fowls in wintertime causing their premature death, these conclusions are confirmed by the results from Cairngorm in Scotland.

Mountain biking in Cairngorms

The Capercaillie is primarily associated with conifer woodlands in Scotland, especially mature Scots pine forests with an understory of heather, bilberry, and cowberry. In the 18th century, the capercaillie became extinct in Scotland, Ireland, and northern England, following extensive felling of pinewood habitats to establish grazing enclosures. However, in the 19th century, the bird was reintroduced in Scotland by landowners with an interest in shooting. In recent years, though, numbers have decreased.

The reasons for the recent reductions in numbers and range are poorly understood, but habitat deterioration, increased predation, fence collisions, and insect shortages in June seem to cause poor chick survival. Since the recent reduction in numbers, there has been a voluntary moratorium by landowners on shooting. However, as in Bavaria, there has been no sign that this has reversed the decline.

To a large extent, the experience of the capercaillies in Cairngorm National Park matches those from the Bavarian Alps. Here, the impact of outdoor activities on their “playgrounds” or “dancing grounds” serves as a reliable indicator that birds do actually inhabit a place. However, the conclusion is that capercaillies avoid mountain bike trails up to 500 meters on each side of a trail, while they only avoid 150 meters from a hiking path. In Cairngorm, this means that only 39% of the forests and 45% of the scrub areas are actually used by the birds, which have contributed to the region’s famous whisky, Capercaillie Scotch Whisky. Half of all dancing grounds were within these untouched areas, and 95% were less than 200 meters from the center of these untouched places. Hiking paths were deemed only half as disturbing.

Capercaillies in Croatia

Croatia is another location, where the Capercaillies are being helped along. In 2019 the Central European Breeding Centre Tetrijeb was officially opened, and in 2022, the project joined Rewilding Europe’s network.

In a geopolitical sense, Europe was and is a peculiar appendix. Turning a physical map of the Northern hemisphere upside down, we cannot fail to see the peculiar promontory which Europe constitutes. As a mushrooming appendix, it crowns Eurasia, the largest continental landmass on earth. Traditionally and for historical reasons, we are used to considering Europe a continent. Nonetheless, this is, at best, an approximation fabricating the idea that Europe is something apart. Moreover, we lose the ability to see its basic geographical properties, which form a genuinely watery seascape.

To the South, surrounded by the Caspian, the Black Sea and the Mediterranean and to the North, The Baltic, the North and the Norwegian Seas, Europe sort of falls into the Atlantic Ocean. Finis terrae west of Lisboa is often considered the westernmost outcrop. However, similar places are located up and down the western coastline, such as the cliff called Finisterra west of Santiago de Compostela, where pilgrims throw their walking sticks into the foaming seas at the exact spot where some believe the remains of St. James landed in his coffin on his rudderless boat. Alternatively, we may point to Land’s End pushing into the Cornwallis Sea from Penwith or the cliffs at Dingle Bay in Ireland. All of these places are truly awe-inspiring. Yet, when we stand on these high cliffs, we are aware of a despairing feeling: we have nowhere further to run. At least, it must have felt like that for some of those wandering people in the Early Middle Ages, who were constantly on the lookout for a place to forge a better future than that offered as slaves to the constant influx of people pulsating through the great steppes of the Eurasian hinterland stretching from China to the Hungarian Plains.

We know from the study of historical languages that on these rocky coasts or marshy islets in the tidal wetlands, the olden people sought refuge – Norse, Frisian, British, Gaelic, Breton, Basque and Galician languages formerly spoken widely, came to be preserved as smaller or larger linguistic pockets in these landscapes bordering the Atlantic Seascapes. Here, they are still revered and (occasionally) spoken. One of these languages – Norse – even became the official language in Scandinavia when “cut” off from its common proto-Germanic roots.

Land relief in Europe shows great variation within relatively small areas. To the south hilly uplands coalesce with more mountainous landscapes which move upwards into the Apennines, the Pyrenees, and the Carpathians, circling the Alps to enter the broad, lower-lying northern plains and the fertile belt of loess. An arc of hilly and mountainous uplands also exists along the north-western seaboard, beginning in southwestern Ireland, continuing through Scotland, and up along the fjord-cut spine of Norway and Sweden.

However, each region or territory contains their own complex features with reliefs, plateaus, and river valleys petering out into deltas bordered by tidal shores and marshy fenlands. In general, the geology of Europe is multifarious and complex and exhibits a wide variety of vistas, from the volcanic landscape of Iceland to the deep Russian forests, the rolling plains of Hungary and the river delta of the Danube feeding the Black Sea.

One of the enduring and distinctive qualities of the different European people was their seafaring traditions and seaworthy capabilities. Evolved through centuries, they went by water on rivers, hugging coastlines or sailing out to conquer their neighbours. Forests and mountains would block and create borders, while water would unite.

Historically, this complex and constantly shifting physio-geographical landscape fostered a multivariate background for numerous people staking out a life and a living which eventually would be different from that of their neighbours in the next valley.

The history of Europe is the history of this nearly unfathomable diversity.
