From 5 - 9 May, BirdLife Switzerland is once again organizing the "Garden Bird Hour". Interested people spend an hour observing birds in their garden or from their balcony, counting and reporting them. In 2020, 7072 people across Switzerland took part in the campaign and counted an impressive 177 different species! Would you also like to take part, but are unsure about species identification? Then register here. Our ornithologists will be happy to help you discover what's chirping on your doorstep! The price is CHF 50 per hour. This money will be used to build nesting boxes that schoolchildren will install in various places in the park.
