After a sunny morning and lunch by a water hole, the clouds gathered and the heavens opened in Buffalo Springs Game Reserve in northern Kenya. It was Friday 13th!
This young Zebra looked suitably bedraggled as he followed his mother, who was oblivious of the weather and content to continue munching.
Note the perfect alignment of several of the stripes on the necks of the two zebras.
