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.”
