It is that time of year when the younger (but not much smaller) elephants are in musth, they can be fairly ill tempered and you need to look out for them.
Musth is described as follows: "Some males showed "tears" streaming down the side of their faces (secretions from temporal glands), and continual dripping of urine onto their legs. Besides these physical changes, there were associated changes in behaviour. Males that were streaming tended to follow females that were in oestrus, and were markedly more aggressive than others."
I have left these photographs untouched to give you the feeling of him getting closer.
