Grey-hooded Capuchin Babbler Phyllanthus atripennis


Justification of Red List Category
This species is suspected to be undergoing rapid population declines based on rates of forest clearance for timber and agriculture. It is therefore classified as Vulnerable.

Population justification
The population size has not been quantified, but it has been described as 'rare to fairly common' (Collar et al. 2020).

Trend justification
The species is suspected to be declining in line with habitat loss. Between 2016-2019, this species's range experienced forest cover loss of 12% (Global Forest Watch 2020). Projected forward over three generations this equates to a loss of 34%. Assuming that the population declines at a similar rate to forest loss, the past and future rate of decline is suspected to fall in the band of 30-49% over three generations.

Distribution and population

Phyllanthus atripennis is found in western Africa where it is found from Senegal and Gambia through Guinea and Guinea-Bissau to Liberia and western Sierra Leone in the dense undergrowth of forest (Collar et al. 2020).


This species is found in dense forest understorey, but can tolerate a degree of habitat disturbance, being found in secondary forest and forest edge (e.g. Gatter 1997).


Clearance of forest for timber and agriculture is still suspected to be leading to at least a rapid decline in this species. Groups may also be taken as food by local people (Collar et al. 2020).

Conservation actions

Conservation Actions Underway
There are no targeted conservation actions known for this species, but it likely occurs in several protected areas.

Conservation Actions Proposed
Calculate a baseline population estimate and monitor population trends. Investigate the species's tolerance to habitat loss and degradation. Protect remaining areas of its habitat.
