Range Description

Ceratogymna elata is widespread in West Africa from Senegal (very small range [Morel and Morel 1990]), Mali, Guinea (c.419 individuals), Guinea-Bissau, Sierra Leone (c.624 individuals), Liberia (c.2,385 individuals), Cte d'Ivoire (c.3,871 individuals), Ghana (c.817 individuals; it still occurs in the east, albeit in very small numbers [Dowsett-Lemaire and Dowsett 2009b], which may not represent a viable population [Dowsett-Lemaire and Dowsett 2009a]), Togo (few records [Cheke and Walsh 1996]), Benin, Nigeria (c.1,625 individuals) and Cameroon (c.2,791 individuals) (Fry et al. 1988, H. Rainey in litt. 2007). It still appears to be locally common in forested areas of Sierra Leone, south-west Ivory Coast and Liberia (H. Rainey in litt. 2007). Additionally, in parts of Cameroon and south-west Nigeria it may also still be abundant, but there are indications that it is declining in many places (Elgood et al. 1994, P. Hall in litt. 1999, Jam 2006, H. Rainey in litt. 2007, 2011, F. Dowsett-Lemaire in litt. 2012). Much of Liberia has been deforested in recent years, so it is possible that while its population is still stable where forest remains, the overall area of occupancy may have declined with loss or degradation of habitat. Recent observations suggest that the species is in rapid decline in Ghana. It appears to have been extirpated from many areas, including Bia National Park (NP), where there have been no records since 1991 (Dowsett-Lemaire and Dowsett 2011a, F. Dowsett-Lemaire in litt. 2012). It has not been recorded at Atewa Range FR since 2005 at least, with perhaps the last confirmed record in May 2002 (per Dowsett-Lemaire and Dowsett 2011b). During a survey of three forest reserves in Ghana (Draw River, Bio-Tano and Krokosua) in October-November 2003, only one large hornbill was recorded in high quality habitat, at a time when such species should have been present, probably indicative of local declines (H. Rainey in litt. 2011). In Togo, it has probably been extirpated from Assoukoko forest, which is the largest area of forest remaining in the country (F. Dowsett-Lemaire in litt. 2012). Overall, the population is suspected to be in rapid decline.
