Mountain: Life at the Extreme (1 Viewer)

I caught a small part of episode three of this series yesterday. It had some tremendous footage of volcanoes in the Andes, but for me the best footage was of white-winged diucha finches nesting in a glacier at over 5500 m. I've read their natural nesting environment is grassland. If you happen to be an expert on the species, perhaps you can help update the information on this site: https://neotropical.birds.cornell.edu/Species-Account/nb/species/wwdfin1/overview

Check out the footage of the birds' nest in the ice here: https://www.bbc.co.uk/programmes/articles/31kqyFzTvWxNSHC0NKDmLGZ/glacier-birds
