The four ton beast has chosen to roam across Africa by daintily skipping over fences instead of trampling everything in its wake. It elegantly lifts its front right leg over the wire, taking care not to touch it, then its left leg before repeating the process with its hind legs. After one final push it is free and ready to hunt for food.The photos show that Nellie clearly has respect for her surroundings and doesn't want to be blamed for any damage. Elephants are known for their intelligence and ability to solve problems - Nellie's antics confirm how true that is.The images were posted on Facebook by Indri Ultimate Wildlife Tours, of Cape Town, South Africa, which said: 'Our feeling when looking at these photographs is one of utter respect.'They will come as no surprise to scientists who have studied elephants brains, particularly when confronted with danger. Their ability to remember means elephants can dodge not just fences but droughts too. The theory is that older females memorise earlier severe droughts and how the elephants at the time survived it.This means they know where to find distant food and water sources giving them a better chance of survival as climate change becomes a real threat to their natural habitats. But Nellie isn't the only elephant dodging obstacles across Africa.A second elephant was also caught on film skillfully having to avoid a electric fence in Mpumalanga, near the Kruger National Park.This time the cheeky little elephant steps over the fence to grab a branch from a much-loved marula fruit tree in the back garden of a house.The elephant is clearly keen to avoid past experiences such as being tangled up or electrocuted by a nasty fence.After having his snack the young male then lifts both legs back over the fence carefully - despite no current being passed through the electric fence.Magdel van den Berg, the journalist who filmed the baby elephant, said: 'It was quite strange to see the elephant do this but it is marula fruit season and elephants love them. He remembered the fence for sure, he is a regular visitor to the area. It was interesting to see an animal think and plan its way around the obstacles, the owner of the property has reported him going as far as their front door, up hills and over more fences. Quite a busy little boy he is.'Sadly not all elephants find it so easy to adapt to their manmade surroundings and can experience horrific accidents while roaming.  In May last year four elephants were killed after they became trapped on a railway line and were hit by a speeding train.The elephants were part of a herd crossing the railroad tracks in eastern India when the express passenger train ploughed into them.Two adult female elephants and one calf were killed at the scene while another died later from its injuries.Dozens of elephants have died in recent years in such accidents as trains run through national parks and forests. Activists have called for trains to lower their speeds through such areas.(dailymail.co.uk)ANN.Az
