The sheer numbers of wildebeest and zebra that cross Kenya's Masai Mara every year are hard to describe and photograph adequately. We saw hundreds and thousands. They simply cover the vast plains.
The river-crossings are always the highlight of any trip. The deep, turbulent rivers that cross these huge plains are dangerous. Not only are the currents strong, but they are infested with crocodiles that lie in wait for an easy meal.
The drama of these epic crossings is incredible to witness. You can feel yourself willing on individuals that get into trouble - and of course cheering if they make it across successfully.
I have seen more than 12 river crossings, but this year for the first time I saw two adult wildebeests taken down effortlessly by huge crocodiles.
Zebra are always more cautious than wildebeest when it comes to plunging into the river. I photographed these pausing at the bank as though they were working on a plan of action. Brings a whole new meaning to the word 'zebra crossing'.
Meanwhile downstream of all the action and apparently blissfully unaware I spotted these hippos taking it easy in the sun!
