Moustached Babbler Malacopteron magnirostre

Dull gray-brown babbler with a white belly. Namesake moustache is often faint and difficult to see. Sooty-capped Babbler is extremely similar but has a darker brown crown, a darker tail, and no moustache at all. Found in lowland and hill forests. Forages at middle and lower levels, clambering around on branches and trunks in small-to-medium-sized flocks, sometimes with other species. Sings a whistled series of descending notes; pairs often engage in duets. Calls include soft chips and raspy notes.
