The Japanese name マミチャジナイ is composed of 眉 (mami, 'eyebrow'), 茶 (cha, 'brown'), and ジナイ (jinai, an old word for thrush). The name describes the bird's prominent pale eyebrow and brownish coloration. The exact historical derivation of ジナイ is uncertain, but it appears in several traditional bird names.
