Puffinus and cold waters. These tubenose birds fly with stiff wings, and use a shearing flight technique to move across wave fronts with the minimum of active flight. Some small species, such as the Manx shearwater, are cruciform in flight, with their long wings held directly out from their bodies. Many are long-distance migrants, perhaps most spectacularly the sooty and short-tailed shearwaters, which perform migrations of 14,000 km or more each year. "Puffinus" shearwaters come to islands and coastal cliffs only to breed. They are nocturnal at the colonial breeding sites, preferring moonless nights to minimise predation. They nest in burrows
Hutton's shearwater Hutton's shearwater Hutton's shearwater ("Puffinus huttoni") or kaikoura tītī is a medium-sized ocean-going seabird in the family Procellariidae. Its range is Australian and New Zealand waters, but it breeds only in mainland New Zealand, in just two remaining alpine colonies in the Seaward Kaikoura Range. Because six other colonies have been wiped out by introduced pigs, a protected artificial colony has been established near the town of Kaikoura. The bird's name commemorates Frederick Wollaston Hutton, a former curator of the Canterbury Museum in Christchurch, New Zealand. A medium-sized (350 g) seabird, with a 75 cm wingspan, it is brown with
