Observing migrating birds and researching migration has a long tradition for our volunteers as well as for the Swiss Ornithological Institute. Our goal is to document migration, identify changes and make data available to support conservation efforts. To achieve this, various sections, ringing teams and work groups are involved in projects that are often long-term. Birds that are either stopping over or in active migration make up about 45% of all records submitted by volunteers on ornitho.ch and entered into the Swiss Ornithological Institute’s database. Thanks to these efforts, migration and the occurrence of migrant visitors in Switzerland are better documented than ever before.
Our Information service receives about 400,000 chance observations every year from volunteer birdwatchers all over Switz ...
Monitoring rare breeding and visiting birds
When and where a migratory species occurs in Switzerland in the course of the year is indicated in our online database Birds of Switzerland.
The presence index per species and year 2000–2021 accounts for the increase in observer activity and allows for comparisons between years.
- The current list of bird species in Switzerland and their systematic order according to the “Handbook of the Birds of the World” can be downloaded here (including an Excel version).
- The ID bulletins provided by the information service (in German and French) and the Chronique ornithologique romande published by Nos Oiseaux (in French) offer syntheses of migration activity.
- Occurrences of rare and unusual species in Switzerland are summarised in the annual reports of the Swiss RC.
