Grey-necked Picathartes, Picathartes oreas, is among 349 species of African birds that are globally threatened with extinction. With the current deforestation and fragmentation of its habitat, this study was undertaken to assess population status and habitat requirements in one such forest fragment, the Mbam Minkom Mountain Forest in southern Cameroon. 90 breeding sites with 207 nests and 24 potential breeding sites were found. From 34 nests with signs of breeding activity, the entire population was estimated to be 68 breeding individuals. Populations were highest in the north west region but had declined from 40 breeding individuals in 2003 to 20 in 2007.
