A small owl species (Otus scops) found across Eurasia. In Japanese, the name is usually written in katakana as コノハズク.
I heard the call of a Eurasian scops owl in the forest at night.
Kanji spelling is rare and may not be widely recognized; the word is usually written in kana.
The name コノハズク (木の葉木菟) literally means 'leaf owl', likely referring to its small size and bark-like camouflage. The exact origin is uncertain.
