missing the neotropics
My impression (though I'm far from expert on Swiss birding) is the sites in the pre-alps that are actually closer to Zürich tend to have some of the montane species (Grouse, Three-toed WP, Pygmy-Owl, though generally not Citril or Snow Finch or Rock Partridge) but the birds are usually hard, there is more disturbance, and you're better off traveling a bit further for better chances.
A good website to give you a good idea of where birds generally should occur is vogelwarte.ch, and navigate to the species profiles then to the maps which are quite useful. IE, here is a heat map for occurrence of the Woodpecker: Birds of Switzerland - Swiss Ornithological Institute
Unfortunately pretty much any interesting bird species is marked as sensitive on eBird, and ornitho.ch has a clunky interface and limits you to 15 days of sightings history, so it makes it pretty challenging to get an idea of where anyone actually sees anything here.
Another trick with birding in CH is then figuring out all the bits about access once you've figured out where you want to go: Can you actually drive there and if so where can you park, or should you / can you get there via train and Postbus. Then are you better off using a ski lift / gondola and if so are the lifts running at that time of year and if so when is the first lift in the morning and such... always a bit of a hassle to figure out all of the logistics for new sites. I'd recommend carrying a bit of cash, some of the mountain lifts and some of the little restaurants don't take card.
