I have two weeks in the above two countries from 20th September. I know it's the end of the rainy season in BF so getting around to the national parks may not be very easy, and that Mali isn't the strongest country in West Africa for birding, but if anyone has any suggestions for places I should try to fit in, I'd be glad to hear from you. One place I'll definitely be going to is Dogon country in Mali, and I know that the cliffs there support a number of species, but beyond that I don't have much idea of what to expect.
