キバネモズモドキ Vireo carmioli

Small yellowish bird; note bold wingbars and face pattern with short pale eyebrow and arc under the eye. Yellow underparts sometimes bright, sometimes paler whitish, but always some yellow tones. Could be mistaken for a tyrannulet but note thicker bill and more horizontal posture. Usually seen singly or in pairs, following a mixed-species flock through forest, edge, and second growth. Found at relatively high elevations in its limited range. Song is a slow series of short phrases, like a squeaky Yellow-throated Vireo.
