Hutton's Shearwater
Puffinus huttoni
Hutton's shearwater (Puffinus huttoni) or the kaikōura 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. Its conservation status is Endangered, because there are just two remaining breeding colonies, located in the Seaward Kaikōura Range. Six other shearwater colonies have been wiped out by introduced pigs. Hutton's shearwater is the only seabird in the world that is known to breed in alpine areas. Conservation measures for the bird include community initiatives to rescue birds that crash-land at night on streets in Kaikōura, and the establishment of a protected area on the Kaikōura Peninsula including a predator-proof fence, man-made burrows, and translocating fledglings from the remaining colonies.
The bird's name commemorates Frederick Hutton, a former curator of the Canterbury Museum in Christchurch, New Zealand. A medium-sized seabird, with a 75 cm wingspan, it is brown with a white underbelly and brown collar, dark borders to the underwing, dark grey bill, and pinkish dark-webbed feet; it can be distinguished from fluttering shearwater by its dark grey "armpits". At a breeding colony it has a loud cackling calls.
