They were sweet black birds with yellow beaks against a sheer snowy white backdrop. I was seeing these birds for the first time & they were close in appearance to crows, but for their beaks. Found them interesting, as they calmly beheld tourists in the midst of the biting cold. And they had no problem being photographed either.
A bit of Google search indicates they are officially the Alpine Chough & are also known as the Yellow-Billed Chough.
