This species is listed as Near Threatened because it is thought to have a moderately small population which is expected to experience a moderately rapid population decline over the next ten years, owing to forest clearance and degradation. Any evidence that it has a small population, or is undergoing a rapid population decline, might qualify the species for uplisting to a higher threat category.

A solid, thick-billed vanga. Males are black-hooded, with the upper breast in addition black; the underparts are whitish and the back grey. The bill is pale blue. Females are similar but the hood covers only the head and the breast is pink- or orange-tinged. Similar spp. Males are distinguished from Ashy Cuckoo-shrike Coracina cinerea and females from Tylas Vanga Tylas eduardi by the conspicuous deep pale blue bill. Hints Rather scarce, apparently most common in mid- and high-altitudes in southern Malagasy rainforest, where it may be found stripping moss off branches in mixed-species flocks. This and the next species share the characteristic Xenopirostris whistle, a loud tseeang.
