snowy owl
Refers specifically to the bird species Bubo scandiacus. The katakana spelling is standard in Japanese.
I saw a snowy owl in Hokkaido.
Katakana spelling is standard for this animal name; usually written in kana.
Kanji spelling exists but is rarely used; the katakana form is strongly preferred.
Compound of 白 (shiro, 'white') + 梟 (fukurō, 'owl'). The katakana spelling is conventional for animal names.
