fjällhuvad glasögonfågel Heleia squamiceps

A small, slim-billed songbird with a green upperside, yellow-washed underparts with green sides, and extensive white streaks on the head. South Sulawesi form shows a scaled throat; all other forms have an unmarked pale throat. Juveniles show a green-toned crown and a paler underside. Pairs or small groups inhabit montane forest and edges, frequenting mixed-species flocks. Confined to Sulawesi. Unmistakable: the only warbler-like songbird with abundant white head streaking. Short, rich warbled song includes repeated phrases like “twit-tiwit…” interspersed with “chu-chu-chu” notes. Call is a soft “chu-chu-chu.”
