In this season, I can often find wild birds in my area. One of representative wild birds is "Mozu". In Kanji character, it is written "百舌". "百" means one hundred, and "舌" means tongue. Why?
Mozu has a habit copying several other bird's voices, so it is called "百舌".
And it has another odd habit. It is called "Mozu no Hayanie".
It hunts several small animals like frog, lizard, grasshopper, and it leaves them on a branch of a tree. Some people say that it saves them to eat later. But, it often forgets them. No one has known real reason.
There is a Autumen's song that almost Japanese have known. "Mozu" appears in this song. You can listen to it, here.
