The Behavior Guide to African Mammals: Including Hoofed Mammals, Carnivores, Primates by Richard Estes has been gathering dust on our book shelf since we purchased it prior to a trip to Kenya in 2000. It's an old book, first published in 1992 and republished with, I understand, few if any modifications in 2010. It's full of information about African mammals. So full, in fact, that there's a lot more than an old codger like me can absorb. Even though I usually skipped sections that did not seem relevant to my upcoming trip to Tanzania, it took me a long time to read.
Material is better organized for a biologist than a laymen like me. Chapters typically begin with detailed descriptions of family traits followed by even more detailed sections about individual species. Species sections often refer back to family sections or other species sections. This organization obviously saves space in a book that is already long, but it makes reading difficult. If you want comprehensive, scholarly descriptions of the behavior of African mammals, this is probably the book for you. If you're looking for a layman's overview of African mammals, I imagine there is a better source.
