觀察細節
This is a conservative estimate only. I was able to count accurately up to 400 birds, but the remaining geese were very tightly packed as they grazed. The 400 counted was well below half the flock. The recording enclosed was made when many of the birds relocated to the salt pond around sunset. Photos will be submitted to reviewer.
