More zebra keeping watch. You never know when a predator might jump out of the brush.

Thousands of wildebeest crossing the river -- frantically hoping they don't get eaten. Notice several begin jumping from a high rock in their panic.

Another part of the river, another group of wildebeest numbering in the thousands. This group hemmed and hawed on the banks for an hour before finally deciding to make a run for it. Luckily for them, no crocodiles were in view.
