Kingdom Phylum Class Order Family
Animalia Chordata Mammalia Cetartiodactyla Bovidae

Scientific Name: Philantomba maxwellii (C.H. Smith, 1827)
Common Name(s):
English Maxwell's Duiker
French Céphalophe de Maxwell
Antilope maxwellii C.H. Smith, 1827
Cephalophus maxwelli (C.H. Smith, 1827)
Taxonomic Notes: Philantomba was formerly regarded as a synonym or subgenus of Cephalophus but is now treated separately by most authors including. Two subspecies have been named, the nominate form occurring over almost all of the range and P. m. danei on two islands off the coast of Sierra Leone (Grubb and Groves 2001, Nett and Newing 2013).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-01-07
Assessor(s): IUCN SSC Antelope Specialist Group
Reviewer(s): Hoffmann, M. & Mallon, D.
The species remains widespread within its historical range, and abundant, adapting well to modified habitats and showing resiliency in the face of hunting pressure. Maxwell’s Duiker will probably continue to exist in large numbers, but even this abundant and resilient species cannot withstand increasing human populations and hunting pressures indefinitely. It has already been severely reduced in numbers or eliminated in those parts of its range with very high human population densities and rates of harvest are known to be increasing over much of its range. This foretells its ultimate fate if current unrestricted snaring and hunting continues, unless some form of management which ensures sustainable offtake rates can be implemented. Bushmeat and other surveys indicate that population declines may be close to or have already reached the thresholds for Near Threatened under criterion A, however until this can be confirmed, the species remains listed as Least Concern.

Geographic Range [top]

Range Description:Widespread within the Upper Guinean Forest zone, in moist lowland forests and extending into the adjoining forest-savanna mosaics (East 1999). It ranges from western Gambia and south-west Senegal east to the Cross River in Nigeria, and including two islands off the coast of Sierra Leone (East 1999, Wilson 2001, Nett and Newing 2013). Their current distribution is probably not much changed from their historical distribution, although much of their original habitat has been modified or lost (Nett and Newing 2013). Not recorded in Mali by Heringa (1990) or Wilson (2001) but may occur there in gallery forests in the savanna woodland zone (Nett and Newing 2013).

Population [top]

Population:Generally abundant throughout the Guinean forest zone. It is the most common duiker species in Côte d’Ivoire, where Newing (2001) recorded a density of 79/km² in a mixed, hunted farmland near Taï N.P.

East (1999) produced a total population estimate of 2,137,000, likely a conservative estimate. Despite its resilience to hunting pressure and its adaptability to degraded forest habitats, its numbers show a general tendency to decrease in many areas, especially as there are few protected areas within its range which receive effective levels of protection and management.
Current Population Trend:Decreasing

Habitat and Ecology [top]

Habitat and Ecology:Occurs in moist lowland forests (primary, secondary forests and plantations) and more locally within riverine forests, forest patches and coastal scrub, and in montane grassland up to 1,400 m in Sierra Leone (Nett and Newing 2013). Much of its original habitat has been destroyed by the spread of settlement and agriculture, but Maxwell's Duiker are particularly adaptable to dense thickets, farm-bush habitats, and it still occurs locally in areas with thick undergrowth or other suitable cover. Thus, it has probably benefited from the destruction of primary forests by adapting well to disturbed habitats and remains widespread, occurring in primary and secondary vegetation and often surviving in close proximity to settlement.
Generation Length (years):4.8

Use and Trade [top]

Use and Trade: Widely hunted for bushmeat.

Threats [top]

Major Threat(s): While much of its original habitat has been modified or destroyed by the spread of agricultural settlement, it adapts to secondary vegetation and farm bush. Its major threats are extensive hunting for bushmeat and expansion of settlements. They are among the most hunted ungulates in much of their range but show considerable resilience to hunting pressure, better than other duikers (Nett and Newing 2013). However they are not resilient to intensive poaching; for example, in the Comoé N.P. in Côte d’Ivoire, high levels of poaching led to numbers of Maxwell’s Duiker declining by more than 90% within 20 years (Fischer and Linsenmair 2001).

Conservation Actions [top]

Conservation Actions: It occurs in virtually all protected areas within its range and is well represented in areas such as Sapo NP (Liberia), Taï NP (Côte d’Ivoire) and Kakum, Bia and Nini-Suhien NPs (Ghana).
