Description
The sombre greenbul (Andropadus importunus), a passerine bird of the bulbul family, is native to the eastern side of Sub-Saharan Africa. It measures approximately 15-18 cm (5.9-7.0 in) in length and is characterized by its olive-green plumage, and slightly paler underparts. A telltale characteristic is a prominent white eye. This species can be confused with similar greenbuls, but can be distinguished by its more sombre coloring, different vocalizations, and the white eyes.
Diet & habitat
This bird inhabits dense undergrowth in forests, particularly loving moist areas. It can also be found in coastal bush, riparian forests, and overgrown plantations. Its diet mainly consists of insects, fruit, and small seeds. The sombre greenbul forages in the understory, gleaning insects from leaves and branches, and is often seen foraging in groups or mixed-species flocks. It is known for its shy nature, often remaining hidden in dense foliage, making it more often heard than seen.
Nesting
Breeding season varies depending on the location but generally occurs during the wet season. The sombre greenbul creates a cup-shaped nest, often built in dense vegetation or thickets. The female typically lays two to three eggs, which are incubated for about 14 days. The fledgling period, before the young leave the nest, lasts approximately 16 days. Notable is their cooperative breeding behavior, where non-breeding individuals assist in feeding the chicks.
Status
The sombre greenbul benefits from a wide range and large, stable population. However, habitat destruction and fragmentation are potential threats, especially in areas of intensive agriculture or urban expansion. It is listed as least concern on the IUCN Red List.
