Surviving this very rare phenomenon is very difficult in the harsh African bush
Dr Mike Chase, Elephants Without Borders
Ecologist Dr Mike Chase, who runs conservation charity Elephants Without Borders, said: "I have only come across three references to albino calves, which have occurred in Kruger National Park in South Africa.
"This is probably the first documented sighting of an albino elephant in northern Botswana.
"We have been studying elephants in the region for nearly 10 years now, and this is the first documented evidence of an albino calf that I have come across."
He said that the condition might make it difficult for the calf to survive into adulthood.
"What happens to these young albino calves remains a mystery," said Dr Chase.
"Surviving this very rare phenomenon is very difficult in the harsh African bush. The glaring sun may cause blindness and skin problems."
However, he told BBC News that there might be a ray of hope for the pink calf as it already seemed to be learning to adapt to its condition.
