The freshwater pond was covered with Water Velvet (Akaukikusaアカウキクサ), which is an aquatic plant in the fern family.
There was an Intermediate Egret (Chusagiチュウサギ) with other herons & egrets.
Towards the closing time for the day, a Common Sandpiper (Isoshigiイソシギ) and a Pintail (Onagagamoオナガガモ) landed on the narrow shore by the observation centre.
And as we were just about to leave, the ranger told us a young Greenshank (Aoashishigiアオアシシギ) had turned up on the freshwater pond.
He is rather a fast eater...!
