We saw more warthogs, including some babies:
Today I also saw some unusual insects.
Later I went and read a book by the pool, where I saw the first mosquito I've seen in Africa. The book was set in Botswana, and talked about snakes more than I would have liked.
Editted to add:
I also learned the difference between male and female ostriches. Male ostriches are black (because they sit on the eggs at night) and femail ostriches are grey (because they sit on the eggs during the day).
And giraffes get darker as they get older.
