Grouse and Rock Partridge – herbivores at the mercy of the weather
The breeding success of grouse is extremely variable, mainly because of weather conditions during the rearing of the chicks. If the weather is cool and rainy, the population declines. Population fluctuations are a typical feature of all grouse and partridge…
Hedgerows and forest edges – valuable structures in farmland
In otherwise open country, hedges provide shelter, nest sites and hunting perches. Forest edges, like all transition zones between different habitats, are especially rich in species. But most hedgerows and forest edges do not offer the habitat quality…
Agriculture has a responsibility for bird conservation
The federal government has defined target and characteristic species that merit special conservation efforts in agricultural environments. Despite the government objectives, these species have undergone a marked decline. The available instruments such…
Deadwood and old-growth stands are essential for birds
Deadwood and old-growth stands are critical resources for a wide variety of species groups. Both have become more abundant in forests of marginal economic importance. Not surprisingly, birds that rely on deadwood and old growth show positive population…
Rock faces – spectacular and valuable places of refuge
Rock faces are unique habitats where specialised birds find nest sites out of reach from predators. For a long time, these refuges were undisturbed. Today, with the growing popularity of leisure activities, preserving their ecological value has become…
Species conservation is necessary and worth the effort
A whole range of endangered species can only be preserved by means of specific measures and projects customised to meet their ecological requirements. Since 2003, the Swiss Species Recovery Programme for Birds has provided added support for the protection…
Waterbirds: where wintering and breeding grounds overlap
In winter, Switzerland’s lakes and rivers accommodate about half a million waterbirds. The populations are much smaller during the breeding season, and only few species breed regularly in large numbers, as suitable breeding habitats are rare. Ducks are…
Is Switzerland with its abundance of water a paradise for fish-eating birds?
Switzerland’s lakes and rivers provide suitable habitat for fish-eaters. Distribution and abun-dance of most larger species have shown a positive trend since 1993–1996, but this could soon change as birds once again face persecution.
Problematic coexistence – sharing our buildings with birds
In many areas, rock faces that provide nest sites for typical cliff-nesting birds such as raptors, swifts and swallows no longer exist or have at least become rare. When humans started to erect «artificial cliffs» in the form of buildings, cliff nesters…
Swiss bird communities in constant change
The massive changes in the landscape on the one hand and the progress in species conservation on the other have also affected breeding birds. Wetlands and their inhabitants have suffered huge losses, the species composition in farmland has changed significantly,…
Alpine Tit and Willow Tit – an example of incipient speciation?
Two forms of Poecile montanus exist in Switzerland: the Willow Tit occurs in the Jura, the Pre-Alps and locally on the Central Plateau, while the Alpine Tit is confined to the Alps. The two forms have a distinct song as well as different ecological requirements,…
The spread of settlements has consequences for farmland birds
Settlements have continued to expand in Switzerland since the 1990s. Some birds cope well with this trend, finding suitable habitat in built-up areas. Others, especially farmland birds, have declined considerably as settlements have spread and the surrounding…
Switzerland needs large wetlands with plenty of water
While the populations of many wetland species have increased, they remain small and unable to compensate the losses that occurred in the past. Besides loss of area and isolation, the main problems are linked to the human influence on wetland hydrology…
Lush and green – too much fertiliser harms birds
Switzerland is a country of verdant landscapes. Fields and meadows are richly fertilised, and mires and woodlands receive more nutrient input than is good for them. In consequence, the habitat of many bird species that depend on low, patchy vegetation…
Birds of arable land caught in a downward spiral
In the past century, birds that breed on arable land have severely declined. The downward spiral continues despite federal programmes to protect biodiversity in agricultural areas, indicating that measures urgently need to be adjusted. Several successful…
Natural disasters give rise to biodiversity
Forest covers about a third of the area of Switzerland, and therefore plays an important role in species conservation. For the past century, forest area has increased and stands have grown denser, while more open areas of woodland with their rich biodiversity…
Richer breeding bird community beyond our border
In neighbouring countries across the Swiss border, there are more bird species, higher densities and more Red List species per kilometre square than on the Swiss side of the border. These differences are explained by the greater number of semi-natural…
