At certain times, many small Cape Buffalo herds coalesce at a major watering site, creating a huge herd of perhaps a thousand individuals. This is what has occurred here.(Eventually, they will probably split up and reform into their former smaller groups). Obviously, the site is chosen because it has abundant water and grass. Many calves will be born. The large aggregation of protective bulls will afford some protection from lions & leopards.The above event shows the buffalo, at sunset--young & old--going to the water for a drink. [Chobe NP, Botswana](To make this scene appear the way I saw it, I 'stitched' several images together. To have used a wide-angle lens would have diminutized the animals & have made a poor representation of what I actually saw). [Chobe River, Chobe NP, Botswana].
