ニシオリーブヒメミツオシエ Prodotiscus insignis

A small, upright honeyguide of forest and forest edge, where it forages for insects and flycatches into the open. Plumage is a relatively uniform olive-green to green, with a paler throat, small pale eye arcs, and bright white outer tail feathers that are obvious when flying out for insects. Similar to Green-backed Honeyguide and Wahlberg’s Honeyguide, but differs in range, in its overall greenish coloration including the belly, and in its clean white outer tail feathers. Voice is little known, but apparently gives a buzzy trill in flight that rises and falls in pitch.
