This photograph of thousands of wildebeest grazing on the great plains of the Maasai Mara also hides one clever zebra.

Wildlife photographer Ingo Gerlach captured this image of the massive wildebeest herd at sunrise - and later spotted the hidden zebra.
The 65-year-old photographer from Betzdorf, in Luxembourg spent around two hours watching and taking pictures of the animals at around 7.30 in the morning.
