Active and noisy inhabitant of foothill and highland forest. Brown with a gray head, white eyering, and a long black arc that extends from just above the bill to the back of the crown. Frequently joins mixed flocks, of which it is often a dominant member. Extremely similar in appearance to the closely related Huet’s and David’s Fulvettas; watch for a grayer throat and paler underparts in the former and an absent or near-invisible brow line in the latter. Song is a quick, sputtering burst of high notes that ends with a brief whistle. Calls are chattering rattles.
