Truly long-tailed, even for a sibia, this bird appears rather dainty and small-headed in comparison with most of its relatives. Gray overall, darker on the wings and tail. Mostly lacks the contrasting patterns of other sibias, with only a small white patch near the wingtip. Forages in flocks in open hill forests, edges, and adjacent scrubby second growth. Despite striking appearance, often heard before it’s seen: listen for its loud chittering rattle.
