Résumé :	The White-breasted Guineafowl Agelastes meleagrides is one of 15 bird species endemic to the Upper Guinea Forests of West Africa. The Tai region in southwestern Cote d'Ivoire probably holds one of the largest remaining populations of this species. We assessed population density in two different sectors in the southern part of Tai National Park and one sector in the N'Zo Faunal Reserve, north of the National Park. The sectors differ in rainfall patterns and hence vegetation type, as well as in previous and past levels of logging and hunting. Line transect surveys were undertaken between 2000 and 2001 with an overall survey effort of 2,883 km. Abundance was highest in the sector with the driest forest type, the N'Zo Faunal Reserve (encounter rate: 0.02 detections km(-1), density: 32.9 ind. km(-2)), where we also observed the largest group recorded for the species so far (38 individuals). The species was almost absent in the southeast of Tal National Park (encounter rate:
