A desert specialist...
..and one of Africa's rarest predators.
The brown hyena.
This ghost town is her home.
Its ruins give her valuable protection from the elements.
She has been here for 15 years.
She's already reared nine generations of cubs.
These two youngsters have reached a critical stage in their lives.
They're four months old,
and now they need regular solid food.
But there is nothing edible in these ruins,
so their mother has to look elsewhere
and may leave them for several days on end.
Brown hyenas may walk over 20 miles a day in search of food.
This is some of the most hostile country on the planet.
