This looks nothing like an Osprey to me Ken. Some other species for sure mate. Would have been nicer with a better HA. It's a great record shot though! :)
I have never been birding in Africa so I don't have any experience of the bird, but I don't think this is a buzzard. An Augur Buzzard doesn't have a bill like that, this is one heavy bill like an eagles. Also a juvenile or sub-ad augur have yellow bill base this bird have dark. I think it's an juv. African Fish-eagle like Ken and the village experts say. Here's an picture on a juv African fish-eagle: http://www.google.com/imgres?imgurl=...1t:429,r:4,s:0
Nice image. Beautiful light, and good controled black/whites, just some small overexposition on the foot. TFS
