This species is listed as Near Threatened because it is suspected to be undergoing a moderately rapid population decline owing to the limited impact on the species of forest clearance in lowland areas. Any evidence to suggest a greater rate of decline might qualify the species for uplisting to a higher threat category.

|Range Description:||Bathmocercus cerviniventris has a fragmented range from Guinea (one record from Sérédou but locally common on the Ziama Massif [Bützler 1996]; also recorded from Pic de Fon and Mont Bero Forest Reserves [H. Rainey in litt. 2007]), Sierra Leone (the Nimini Hills, Kono district, also Sandaru and probably Kankordu, and the Kangari Hills [Okoni-Williams 2001], but apparently highly local [P. Robertson in litt. 1998]), Liberia (from the coast to the northern highlands, being frequent on Mt Nimba) (Gatter 1997), Côte d'Ivoire (Mt Nimba and Sipilou in the west, Taï National Park where its preferred habitat is rare [Gartshore et al. 1995], Marahoué National Park [P. Christy per L. D. C. Fishpool verbally 1998], and Gagnoa and Lamto in the south), and Ghana (very few records). In Côte d'Ivoire, future surveys may well locate the species in Mt Peko National Park and mountains east of Mt Nimba (H. Rainey in litt. 1999). In 1997, in Liberia, on the basis of survey density estimates, the population was calculated to be at least 60,000 pairs (Gatter 1997); however, throughout much of its range it would appear to have an extremely local distribution.|

|Population:||The global population size has not been quantified, but the species is described as locally common (del Hoyo et al. 2006).
Trend Justification: The population is suspected to be declining moderately rapidly owing to ongoing habitat destruction.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It is found in dense secondary vegetation bordering small creeks and rivers in various forest types (primary and secondary forest, swamp forest, gallery forest, sub-montane forest) and, more rarely, lowland forest (Gartshore et al. 1995, Gatter 1997, Urban et al. 1997). On the Ziama Massif, Guinea, it occurs in humid, open sites near old clearings within mature forest (Bützler 1996). It forages near the ground, always in pairs, on invertebrates (Bützler 1996, del Hoyo et al. 2006). A recently-fledged chick was observed in Sierra Leone during late June, suggesting laying in May (del Hoyo et al. 2006).|
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Generation Length (years):||3.1|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||Due to its specific habitat requirements the species is probably not at high risk from lowland commercial logging activities. However, such logging will affect adjoining habitat and may cause disturbance, as well as potentially damaging catchment areas and affecting habitat through run-off (H. Rainey in litt. 2007).|
