Swiss Alps wildlife, documentary film

This 19 June 2020 video says about itself:

The Swiss Alps: Wild Animal Paradise | Free Documentary Nature

Gentle, green meadows, rugged rock faces, mysterious lakes, dense forests, tall mountains, low-lying river deltas, quietly meandering mountain streams and smack dab in the middle, a unique fauna – THIS is Switzerland! We trace the elementary power of nature and present animals and plants in landscapes that have hardly ever been touched by mankind.

Switzerland is an alpine country, but it is also Europe’s surge tank. Rivers such as the Rhine and the Rhone have their sources here. Glaciers, crevasses, icy cold caves and the underwater dome of the Verzasca are the unusual settings we chose for this film. We meet with rare, selected animal species and present their behavioural patterns, such as the Swiss or Arven jay [meaning the spotted nutcracker], the lynx and albino catfish. Cold, wind, snow and extreme locations demand adaptation that make us marvel.
