Raptors at Risk: Proceedings of the V World Conference on Birds of Prey and Owls - South Africa, August, 1998. . In Africa, the pioneering population monitoring of eagles in Kenya by Brown and in Zimbabwe by Gargett are noteworthy. Furthermore, the consequences of habitat fragmentation and isolation on bird communities, currently a deep concern, have been thoroughly analyzed in temperate forests, as well as in tropical forests but rarely in Africa and never specifically on a raptor community. Raptors are highly sensitive to prey availability, vegetation structurem pollution and human disturbance and thus are good indicators of environmental changes.
