影音備註

A flock of 12 or so black-billed gulls standing in shallow water - possibly the same flock as ML647601212. They were mostly silent, except when another gull was flying in to join them. The approaching gull would call as it approached, and one of the gulls on the water would respond. This happens a couple of times in the recording. Pied stilt prominent in background, black swan also heard. 200Hz hpf used to reduce wind noise.
