I had been observing the Mfuwe Lodge pride while they slept off a feast from a buffalo kill the night before. When this female got up and walked off, I anticipated that she might be going for a drink, so I headed for the nearest waterhole. Sure enough, the lioness appeared through the tall, rainy-season grass and hunched down to drink, occasionally looking up. I managed to capture her gaze and her tongue at the same time.
