I was there a fortnight ago and in the course of a week, in the desert around Damaraland,and on the Skeleton Coast, saw: giraffe, the desert elephant, ostriches, oryx, springbok, brown backed jackal [hanging around the seal colonies on the Skeleton Coast], wild donkeys, hyena as well as kinds of unusual birds.
On a day trip to Etosha, had 3 separate sightings of lion, black rhino, white rhino, giraffe, zebra, wldebeest, kudu, springbok, oryx - all in profusion. Also myriad sub-endemic birds.
At Etosha,the game has to congregate around the waterholes so you just park and watch them all come to you!
That's why the best time to go is during the dry season - May to early December. you'll see far more game than you imagine possible and in amazing environments.
Our trip was organised by Rainbow Tours, based in London (rainbowtours.co.uk.
The best part was the awesome desert landscapes.
Best wishes,
