觀察細節
While watching a single direction I conservatively estimated 50 birds per second flying past my field of view in the same direction. This makes 3000 birds per minute. This density continued to fly past for full 20 minutes (60 000 birds), then slowed to about 20 birds per second, which is 1200 per minute, for another 10 minutes (another 12000 birds). This was just on one point of the island near the lightkeepers house, looking to the south. Likely the same scene was playing out on the entire island. A few crash landings nearby and the sound of the birds calling in the scrub at the burrows increased in volume the whole time.
