The noise and color of 100-300 large macaws and 500-1,500 Amazon parrots and other birds eating clay along riverbanks in the Peruvian Amazon is surely one of the world's great wildlife spectacles, but there is still quite a bit of confusion about which clay licks to visit and what the advantages are of visiting different clay licks.
Macaw and parrot clay licks are special deposits of clay along riverbanks or sometimes in the interior areas of the Amazon rainforest. The birds flock to the clay, usually in waves that start at 6:00 or 6:30 am and end at 11:00 am or noon, to eat thumb-sized lumps each day. The clay appears to detoxify the nasty poisons in their diets of seeds of rainforest trees and vines.
