Up in the rugged, unforgiving mountains of Scotland, can any wildlife make a living? This BBC free full-length documentary film is presented on YouTube by AnimalLife. In these Scottish hills, we see that red deer and pine martens join many hardy bird species such as black-throated divers, hooded crows, ptarmigans, and reintroduced sea eagles. Follow a family of divers from a late second laying to the fledging and beyond. And follow the migration of salmon to the highest points in the river. At the end of the film is an entertaining filming diary.
