Motu Nui, with the smaller Motu Iti and the sea stack of Motu Kao Kao. This was the site of the "Bird Man" ritual, a competition to collect the first egg of the manutara. This took place starting from Motu Nui where the Hopu (representatives from each clan) waited for the sooty terns to lay their first eggs of the season. The Hopu who seized the first egg raced to swim back to Easter Island, climbed the cliffs to Orongo and presented the egg to their sponsor in front of the judges at Orongo. This gave their sponsor the title of Tangata manu and great power on the island for a year. Many Hopu were killed by sharks or by falling. The winning clan gained certain rights, including the collecting of eggs and young birds from the islets.
