観察結果の詳細
Minimum number counted and estimated. Only 19 of the birds were observed on or over the bay. The rest were feeding at the tidal pond, with the astronomical low tide cycle. I was able to obtain a fairly accurate count of 309 birds at the north half of the pond. However, the birds at the south end of the pond were much more bunched up, especially along the marsh edges at the very south. I attempted a rough count, and there were easily at least 450 birds there.
