One of the strangest things I saw during my trip to Namibia was giraffe chewing on dry bones.
I thought that perhaps they could be extracting minerals from the bones because I saw it on several different occasions. Anybody else know what the reason could be?
This was the first wild giraffe my two-year-old daughter had seen so she now thinks all giraffes eat bones.
As we left our camp at Okaukuejo one morning we were greeted by this bull elephant. It seemed appropriate to stop and give way to the larger vehicle.
And these giraffes rowed up in order of size for me.
Zebra's always make a wonderful composition, here they were jostling for best position at the waterhole.
This ground squirrel caught my eye as he groomed his tail. Their tales are very important since they use them as sun shades to protect themselves from the harsh African sun and as shields against snake attacks.
This large bull elephant seemed as tired. It looked as old as the desert landscape that it belonged in. 
I watched as he broke up a scuffle between two young elephants, but then, as he passed through, the mischievous young elephants rammed him from both sides. 
As the elephants came to the waterholes they would drink, have a mud bath and then talc themselves down with dust. 
It looked as though this large elephant was passing on some of his wisdom to a younger bull.
This herd of elephants were breeding and the large bull in the middle appeared to be the most popular with the ladies. I watched as he went round and greeted each cow elephant in turn. 
On this night the elephant kept scenting the evening air. There were lions roaring in the background and the next day we saw why: just outside camp were more than 20 jackals on an elephant carcass.

The waterhole was fed from a bore hole and in this picture the rhino is standing over the outflow, where the freshest drinking water was. This elephant knew where the spot was too and easily won out in the standoff that followed.
It was wintertime when I visited Namibia and the countryside was dry, so all the action took place at the waterholes. Day and night these life-giving pools were a hive of activity as animals and birds came to drink.
Among the most fascinating to watch were the elephants.
These two were so funny, tugging at each other's ears.
And this little one caught my eye as it charged gleefully around in the dust.
These two appeared to be having a quiet chat, before, shortly afterwards, they began a mock fight.
Whilst these two young bull elephants were testing each other's strength.
It is rare to see rhino during the heat of the day, but after dusk they would come to the waterholes to drink. There was a waterhole directly below the second camp that we stayed in, at Halali, and I was able to wait up each night for them - sometimes I was there until 11pm.
The rhino below was in poor shape. It appeared to have lost both ears and part of its tail was missing - I suspect that as a calf it had been caught by lion. It was good to see that it survived. 
Although the black rhino population is more secure than it has been in the past, conservationists now face a far more dangerous and better equipped form of poacher than ever before and keeping them safe has become harder than ever. 
As I kept watch one evening, a black rhino appeared just as dusk fell, followed, almost immediately, by Africa's most elusive cat, the leopard. It was like waiting for a bus to come and then two appearing at once - I didn't' know which way to point my camera.
We stayed in three different camps each close to a waterhole. Our first camp was at Namutomi and it was whilst on a drive from this camp to a waterhole named Kalkheuwel that we spotted the lartest herd of elephants I have ever seen.
We had seen the herd as it was making its way towards the waterhole earlier and so we got there first and then counted the elephants as they arrived. There were at least 80. Once they had drunk, the elephants were fun to watch. They are so playful.
This little one 'bravely' charged at a male impala, knowing it had an 80-strong back up team behind him!
Drinking at a waterhole can be a little less comfortable for giraffe. They are very vulnerable to lion attacks as they bow down and can be very tense as a result. This photograph shows the water spraying from the giraffe's mouth as it raises its head - the water spray is hard to see with the naked eye.
