Elephants in Botswana

I took this photo in Chobe National Park in Botswana. The park is over-populated with elephants to such a degree that many are shipped out to other parks. I noticed this herd standing still and as you can see they are protecting an ill infant, probably about three years old. The mother is stood directly over her baby. The next morning the herd had moved on, hopefully with the youngster fully recovered.
