guldunsanger Macrosphenus flavicans

An unusual warbler with a long bill and yellow eyes. Brownish above and dull yellow below with a gray head and whitish throat. Found in rainforest, mainly in dense tangles at middle levels, usually in pairs or small groups. Similar in appearance to other longbills, but with a good view, separated by the coloration of the underparts. Most often detected by the distinctive song: a long series of clear whistled notes in which each note is slightly lower in pitch. The pattern is similar to that of Sabine’s Puffback, and the individual notes sound very batis-like.
