three different cuts from a displaying bird. The first is of song during a prolonged flight display by a bird over a gravel beach/spit adjacent to a frozen bay. Various sounds in this cut, with most of the vocs being 'rhthymically repeated calls', but also what BNA calls 'song' at 0:04 and 1:05 blending into 'chatter' each time. While displaying the bird was high in the air flying with rapid, shallow, fluttering wingbeats and moving in a large, slow circle. The second is of calls in a high chase flight from three birds, one of which was the same individual as in the previous cut. The third is of song and various call types during a prolonged flight display from the same bird
