Japanese scops-owl
A small owl species native to Japan; scientific name Otus semitorques. Typically written in katakana as a species name.
I heard the call of a Japanese scops-owl in the forest at night.
screech owl (Otus asio)
Katakana spelling is standard for this bird name; usually written in kana.
Kanji spelling is rare and mainly encountered in specialized or older texts.
Formed by prefixing 大 “large” to コノハズク, the name of the Oriental scops-owl, to distinguish this larger related owl.
