Standard katakana spelling for this bird name.
Kanji spelling is rare and mainly seen in formal or scientific contexts; the word is usually written in kana.
The name combines 山原 (Yanbaru), the forested region of northern Okinawa, and 水鶏 (kuina), an old Japanese word for rail (a type of bird). The exact derivation is straightforward from the place name and the bird's classification.
