Swiss Breeding Bird Atlas
The Breeding Bird Atlas 2013–2016 will accurately depict the distribution and density of all Swiss breeding birds.
After 1972–1976 and 1993–1996, a new bird census is being carried out from 2013–2016. During these four years, around 1000 volunteer birdwatchers will explore the whole of Switzerland and the Principality of Liechtenstein to map the breeding birds.
As the forerunners, the new Swiss Breeding Bird Atlas will be a milestone for research on and conservation of birds in Switzerland. By depicting the occurrence of all bird species breeding in Switzerland, the atlas will be an invaluable basis for the assessment of the status and trends of all Swiss bird species and for targeting the conservation of endangered species. The project will stimulate ornithology in Switzerland in similar ways as the atlas project in the nineties did.
The following main results will be compiled. The level of detail will allow statements at the regional scale as well.
- Current distribution (10 x 10 km grid) and trends in distribution since 1950–1959 (10 x 10 km, for 100 species), since 1972–1976 (10 x 10 km) and since 1993–1996 (10 x 10 km and 1 x 1 km)
- Density (modeled for 1 x 1 km) and its trend since 1993–1996
- Population size for each bird species in Switzerland
- Altitudinal distribution and its trend since 1993–1996
- Significance of the different habitat types for specific species
