The actual delivery was very fast - a few seconds and the calf was lying kicking to free itself from the sac on the ground. The mother initially moved away, rumbling excitedly...and the rest of the herd responded immediately, rumbling, trumpeting and rushing to the scene.
This was certainly a day to remember, and probably the highlight of my career as a wildlife photographer, safari guide & operator.
