Visiting a clay lick is one of the most mesmerising sights you are likely to experience during a trip to Peru. After patiently waiting at their preferred feeding time, it is likely that these colourful species will gingerly approach the clay lick to feed. After the first brave few arrive, hundreds more often follow and the wall becomes a hive of activity. The clay is said to neutralise toxins in their diet, or arguably it is said the birds simply require more salt in their diets. Either way, it is a special sight not to be missed.
