Friendly Bush Warbler Locustella accentor

Though frequently derided for the reputed inaccuracy of its name, this mouse-like bird can prove quite confiding. It is, however, generally quite difficult to see in dense undergrowth; best detected by its song, a series of three piercing whistles, the last of which is long and grating. If seen, note dark brown plumage, speckled gray throat and chest, and long broad tail. Found on only a handful of forested mountaintops in Borneo’s Crocker Range, where it skulks about in tangled mossy areas with extensive fallen debris.
