Why do emus live where they do?

Emus need open country, so tend to live in grasslands and open bushland and heath, where they can run easily. They live wherever the food source is sufficient, and have been known to move to where rain has fallen and food is being replenished, hundreds of kilometres away. Emus need water regularly, so cannot stray far from waterholes and water courses.
