Our Information service receives about 400,000 chance observations every year from volunteer birdwatchers all over Switzerland. For many species this provides reliable information on their spatial and temporal patterns of occurrence as well as on population trends.
Since about 1960, our Information service has been systematically collecting opportunistic observations of birds. The Ornithological Institute benefits from the observation efforts of more than two thousand volunteer collaborators, many of them experts with sound skills in field ornithology and extensive knowledge of Swiss and European birds. These invaluable collaborators record their observations on our online birding platform ornitho.ch. In exchange they receive a bird information bulletin twice a year, which contains a summary of the most noteworthy bird observations made in Switzerland during the past four months as well as calls for special collaborations and further information.
You can record any remarkable sightings directly at ornitho.ch
The Swiss Federal Office for the Environment FOEN supports our database and thus obtains access to the data contained therein.
