According to an Aztec myth, the war god Huitzilopochtli sent a group of Mexica on a journey to establish the new center of the world. After some two hundred years of wandering, they saw an eagle resting on a cactus with its “wings stretched outward like the rays of the sun.” Taking the bird to be a divine sign that they had reached their destination, they “began to weep and dance about with joy and contentment.”

While conducting research in the remote Iranian region of Khuzestan in the 1970s, folklorist Grace Goodell found that villagers refused to hunt any “unusual” migratory birds that stopped in the area for only a few days, believing them to be performing a hajj pilgrimage. Based on migration patterns, the birds may indeed pass over Mecca on their way to Africa, Goodell noted, although “probably few actually winter by the house of God.”
