iriomotemeis Sittiparus olivaceus

Reddish-brown songbird with a black crown and throat and olive-gray wings. Resident in broadleaf evergreen forests, especially in higher elevations, but poorly known. Endemic to Iriomote and Ishigaki Islands, in the southern Ryukyu Islands. Formerly considered conspecific with Varied Tit, and plumage intermediate between Varied Tit and Owston’s Tit, but neither has Iriomote’s olive wash on wings. Song resembles Japanese Tit, and nasal call recalls Varied Tit but drier.
