このサギは興奮すると羽毛を逆立て体全体を大きく見せる動作をする。この動作は近くにクリバネコウウチョウの群がいたためかもしれない。
There are also features on how to walk; the bird is looking for prey on tiptoe. This heron does an action to ruffle the feathers when excited and makes the whole body looks big. The action of this time may be because there were a group of Grayish baywings nearby.
