I have recently visited the Game Parks in Southern Africa and the is THE book to have with you. It lists all the animals, birds, plants, trees and anything else you could wish for in the natural world with a full description and a picture to enable full identification - and all in one book. Buy it!
This was a good book to take on my safari holiday. It has a bit of everything. I didn't give it a five star rating as the colours in the book don't always correspond to the animals, particularly the birds, and it would have been good to have some more information on the animals (e.g. behaviour). All in all a good general, all round guide. I would recommend taking a specialist bird book as well.
This book was just great. My cousin and I used it when we drove across Africa. We kept it by us in the centre consol of our Land Rover and if we didn't recognise anything this book generally helped us out.
