A small, inconspicuous, gray-green bird with striking white outer tail feathers that are evident in undulating flight. It is easily confused with other honeyguides, but a pale spot on the top of the bill and subtle, darker (moustachial) streaks on either side of the throat are characteristic. Often it is the commonest honeyguide in mixed woodland, cultivation, and pasture; it can be tracked down by following its continuous, strident “swiiit, swiiit, swiiit” calls. Thick-billed Honeyguide (not recognized by some taxonomies) is almost identical, but it is darker in coloration and prefers closed-canopy forest. The smaller Least Honeyguide is often more heavily streaked underneath, and Pallid Honeyguide has a plainer face and indistinct moustachial streaks; both have differing vocaliations.
