Lion/Lioness Mating (4th image): The lion slinks off and lies down several feet away. They both rest. [Xakanaxa, Botswana].
Three Lionesses resting beneath a tree: The one on th left is the youngest, probably only 3 years. Note that she still has distinct dark bars on her legs. The one in the middle is probably 6 months older. The oldest being the one on the right. Thus they are probably siblings from different matings. [Botswana].
The premating behavior is depicted in these two images. If the lioness is not ready, she will snarl and act agressively towards the male. [Botswana].
