媒体文件注释

natural vocalizations; 'song' from a male bird perched on a prominent rock above a recently predated nest, on a cliffy talus slope in alpine tundra. While singing the bird would droop its wings slightly and quiver them at a nearby female. Part way through the cut the female flies off a ways and the male follows her, continuing the display but singing much more quietly.
