The White-browed Crombec, *Sylvietta leucophrys*, is a diminutive and distinctive member of the African Warbler family (Macrosphenidae), inhabiting the dense montane forests of East Africa. Measuring approximately 10-12 cm (4-5 inches) in length and weighing a mere 8-12 grams, this compact bird is characterized by its olive-green upperparts and a striking, well-defined white supercilium that contrasts sharply with dark lores and ear-coverts. Its underparts are a dull greyish-white, transition...
Found primarily in montane and submontane evergreen forests, often favoring dense undergrowth, secondary growth, and forest edges. Typically occurs at elevations ranging from 1,200 to 2,800 meters (4,000 to 9,200 feet).
Primarily insectivorous, feeding on a wide array of small invertebrates including caterpillars, beetles, spiders, and other arthropods. Forages mainly by gleaning and probing dense foliage and bark surfaces.
Highly active and restless, the White-browed Crombec forages constantly during daylight hours, often roosting solitarily or in pairs within dense foliage. Its primary foraging strategy involves gleaning small invertebrates from the undersides of leaves, twigs, and bark, frequently hanging upside ...
