Wildlife
Our trip centred on the wilderness areas for the wildlife of southern Africa, particularly its abundant bird life with approx. 1123 species within our trip area and 842 seen - plenty of reasons to revisit.
Our mammal trip list stands at 101, but includes 2 road kill - aardwolf & brown hyena. Even those with only a passing interest in the wildlife cannot but be impressed by the size, variety and numbers.
EQUIPMENT
Would certainly recommend taking binoculars but in my opinion a telescope is reasonably impractical and could be considered a luxury - takes up a lot of room and most wildlife is large and in parks most viewing is done from the vehicle.
Take a decent camera with plenty of storage or computer to download - a spare battery is sensible as is a means to charge on the go. We used our 240v inverter.
Since the advent of cheap wildlife cameras that work on warm blooded movement and can operate at night I would now take one to set up in camp - out of reach of hyenas and other inquisitive creatures.
