You're in luck if you spot these Swiss birds

The Swiss Ornithological Institute (SOI), that is celebrating its 100th anniversary this year, has come up with a Swiss bird list for those wishing to add some feathered wonders to their Swiss wish list. In early April of 1924, a group of bird lovers gathered to inaugurate the observation hut on the southern shore of Lake Sempach in central Switzerland. Alfred Schifferli was the visionary behind the SOI and became its first director. The coordination of bird ringing was one of the bird SOI’s initial main tasks. In addition, it built a reference library with ornithological writings for study purposes to collect knowledge about birds and make it accessible to everyone. With growing financial support from the public, the SOI was given a newly built building on the lakeshore around 1955. At this time the SOI was transferred to a non-profit foundation. It now receives 40,000 visitors a year, and the free information service receives several thousand emails and telephone calls every year.
