Range extension of the Nahan’s partridge (Ptilopachus nahani) in Cameroon evidenced by camera traps

Nahan’s Partridge Ptilopachus nahani is a lowland forest bird species, classified as Vulnerable. This study reports new camera trap detections in southeastern Cameroon, suggesting a potential westward range extension of over 1,000 km, given that the nearest known population is located in western Uganda. Between May 2016 and December 2023, six detection events confirmed the presence of at least nine distinct individuals within semi-deciduous logged forests. These findings highlight the need to update distribution maps and conservation strategies for this vulnerable species. Future ecological and genetic studies are essential to clarify the species’ full range, assess population connectivity, and guide conservation efforts.
