The South American Odyssey

The Tangata manu ("bird-man," from tangata"person, human being" + manu "bird") was the winner of a traditional competition on Rapa Nui (Easter Island). The ritual was an annual competition to collect the first sooty tern(manu tara) egg of the season from the islet of Motu Nui, swim back to Rapa Nui and climb the sea cliff of Rano Kau to the clifftop village of Orongo. The race was very dangerous and many hopu (assistants of the contestants) were killed by sharks, by drowning, or by falling from cliff faces, though replacements were apparently easily available.
Once the first egg was collected, the finder would go to the highest point on Motu Nui and call out to the shore of the main island, announcing his benefactor by that benefactor's new name and telling him, "Go shave your head, you have got the egg!" The cry would be taken up by listeners at the shoreline who would pass it up the cliff side to the contestants waiting in the stone village. The unsuccessful hopu would then collectively swim back to the main island while the egg-finder would remain on Motu Nui and would fast alone until he swam back, which he would do with the egg secured inside a reed basket tied to his forehead. On his reaching land, he would then climb the steep, rocky cliff face and, if he did not fall, present the egg to his patron, who would have already shaved his head and painted it either white or red. This successful contestant (notthe hopu) would then be declared tangata-manu, would take the egg in his hand and lead a procession down the slope of Rano Kau to Anakena if he was from the western clans or Rano Raraku if he was from the eastern clans. The new tangata-manu was entitled to gifts of food and other tributes (including his clan having sole rights to collect that season's harvest of wild bird eggs and fledglings from Motu Nui), and went into seclusion for a year in a special ceremonial house. Once in residence there he was considered tapu(sacred) for the next five months of his year-long status, and allowed his nails to grow and wore a headdress of human hair. He would spend his time eating and sleeping, and would be expected to engage in no other activity.
The Birdman cult was suppressed by Christian missionaries in the 1860s. The origin of the cult and the time thereof are uncertain, as it is unknown whether the cult replaced the preceding Moai-based religion or had co-existed with it.
At the viewpoint of Rano Kao, there is a rock with 3 Birdman petroglyphs each on one the sides. Indicating the close association this ritual had with this place.もっと詳しく
