Macrosphenus kempi
Kemp's Longbill (Macrosphenus kempi) is a small, highly cryptic passerine belonging to the family Macrosphenidae, the African warblers, a group distinguished by their somewhat enigmatic classification and specialized adaptations. Measuring approximately 12-14 cm in length and weighing around 12-18g, this inconspicuous bird possesses a remarkably long, slender, and slightly decurved black bill that serves as its namesake and primary field mark. Its plumage is generally drab, with a plain olive...
This species primarily inhabits the dense undergrowth and tangles of tropical and subtropical lowland moist forests, often near forest edges or clearings. It prefers areas with a thick shrub layer, typically found at elevations from sea level up to around 1,500 meters.
The diet consists primarily of small insects and other invertebrates, such as spiders and larvae, which it gleans and probes for in dense foliage and bark crevices.
Kemp's Longbill is an exceptionally shy and secretive bird, spending most of its time gleaning and probing for prey within dense vegetation, often close to the ground. It forages solitarily or in pairs, sometimes joining mixed-species foraging flocks, using its specialized long bill to extract in...
Kemp's Longbill has a disjunct distribution across tropical West and Central Africa, primarily inhabiting the Guineo-Congolian forest biome. Its range extends from southeastern Ghana and Togo eastward through southern Nigeria, Cameroon, Equatorial Guinea (including Bioko Island), Gabon, and the R...
