Night heron,Goisagi,ゴイサギ

I think that Night heron to be a kind of smart wild bird which sometimes use a twig as a tool for capturing a small fish.

They capture small fish at the moment when they trace the surface of the water with the twig which they had in their mouth to a bill, and a small fish escaped.

Because water lilies grew thick, They do not see the surface of the water. Therefore the Night hero cannot catch a small fish.
