brown dipper
A bird species (Cinclus pallasii) found near mountain streams in Japan. The name literally means 'river crow'.
The brown dipper is a bird that lives in clear streams.
Kanji form is rare and mainly used in scientific or literary contexts.
Compound of 川 (kawa, 'river') + 烏 (karasu, 'crow'), from the bird's dark plumage and riverine habitat. The exact derivation is uncertain.
