For most animals, life in the bush is not a walk in the park. You always have to be on high alert and vigilant about danger lurking behind every tree or bush to come and get you. So, to steer clear of predators some animals stay close together—safety in numbers—and they make sure to choose open terrain, so that they are not easily surprised by an ambush. They make the most of the different skill sets that each of the animals brings: some have good hearing, others have better sight or smell, so sticking together can really help a lot.
Besides the different plains on the reserve, there is another excellent place for animals to have a great overview of the surroundings. And that place is our airstrip, where we often find animals in a congregation, strolling and eating grass on the borders of the airstrip. The only danger that can befall them here is the occasional incoming flight, but with the noise of a small aircraft (and the people on the ground making sure there are no obstacles on the airstrip) the animals are long gone before touchdown.
