Black-and-white-casqued hornbills are found in forests and savannas throughout West and Central Africa. The subspecies Bycanistes s. subcylindricus ranges from Sierra Leone and northeast Liberia across the Ivory Coast to western Nigeria, and the subspecies, B. s. subquadratus, ranges from eastern Nigeria, Cameroon, and the Central African Republic to Sudan, Zaire, Uganda, southwest Kenya, and northwest Tanzania (del Hoyo et al., 2001). An isolated population of B. s. subquadratus also exists in Angola (Lewis and Pomeroy 1989).
