@Andrew Swales is this a security thing for them - since they're used to surveying the surrounding territory, they become anxious or distressed without having an elevated viewing location?

I'm not sure if it could actually be said they become 'anxious or distressed' - but, from our experience if given the chance or choice, they will always keep at least 'half an eye' on the distance. Presumably for a transient, nomadic spp their prey, their potential mates, and their many threats, will always come at ground level and from a distance. They have hugely powerful eyesight and can seem to look straight through you whilst focusing on something a human can't see or spot, many, many hundred of meters away. Given the chance to lie up on a high platform, most will spend a large part of the day there.
So my personal answer to your question, is that I have no proof other than our own observations of behaviour, but my gut feeling is 'probably'...
