呼ばれると鳥かごから出てきて芸をして、終わると鳥かごに戻るインコ

　飼っているインコが、飼い主のテーブルをコインで叩く事で、鳥かごの扉を自分で開けて出てきて、色々と芸を披露し、終わると自分で鳥かごに戻る様子です。
　何の褒美も無いのに、中々芸達者なインコです。

By tapping the owner’s table with a coin, the parakeet will open the door of the birdcage by itself, come out, perform various tricks, and return to the birdcage by itself.
“Even though there is no reward, it is a parakeet that is quite a performer.”
