Some seabirds travel great distances from their nests in search of food. This is the track taken by a southern royal albatross (given the name Princess Anne) from her nest on Campbell Island to the Chatham Rise. Information about her movements was supplied by a tiny satellite transmitter and a recorder fitted to her body. She travelled for almost 16 days, while her mate took his turn sitting on the egg. She covered the first 900 kilometres in 24 hours – an average rate of 37.5 kilometres per hour. Her furthest point from the colony was 1,200 kilometres, but she flew a total of 6,000. Just over half of her time was spent in flight; she sat on the water for the remainder.
