several cuts from the same bird, mostly in flight display near a small lake surrounded by open, dry alpine tundra. The first cut is of 'rhythmically repeated calls' (RRC) from the bird during a prolonged flight display in which the bird flew in a very large circle while rapidly fluttering its wings, high in the air (at times barely visible). The second cut is what I believe this is what BNA calls song, here given in a low flight over the edge of the lake. The third cut is of song and RRC, the song was given as the bird took off from the edge of the lake and began its display flight, with the long series of RRCs continuing for the rest of the display as the bird slowly got further away from me. The fourth cut is of RRCs, given from lower down and closer than most of the flight displays by this individual.
