Hoopoe (multiple cultures)
Hoopoes are distinctive birds and have made a cultural impact over much of their range. They were considered sacred in Ancient Egypt, and were "depicted on the walls of tombs and temples". There are many stories about the hoopoe bird as a messenger. In fact, the hoopoe appears in the Holy Qur'an carrying messages between King Solomon and the Queen of Sheba.
The Hoopoe is present in ancient Egyptian art where it is depicted as a protector of tombs and a symbol of royalty. The Hoopoe is often combined with solar motifs and is associated with kingship and fatherhood. In tombs, the Hoopoe is considered a guardian which protects the spirit on its journey to the realm of the dead.
