A meerkat sentinel is safari reduced to its smallest act of seriousness. One animal rises upright above the grass or salt-pan scrub, paws tucked close, black-rimmed eyes scanning the horizon while the rest of the group feeds below. There is something almost comic about the pose at first — neat, vertical, improbably alert — until you realise how complete the vigilance is. In the stillness of the Kalahari and the Makgadikgadi, this tiny watcher becomes the whole mood of the landscape: exposed, bright, vulnerable, and entirely alive to what might appear next.
