A pack of African wild dogs in Botswana's Okavango Delta enter a water pan in pursuit of wildebeest. In this region wild dogs do not usually take adult wildebeest but they will test animals to see if they can make them run or separate the calf from its mother. In this case mother stands her ground and keeps her calf safe against a dramatic backdrop of an approaching storm. Filmed by remarkable guide Diesel at Bushman Plains camp.
