Hutton's Shearwater Puffinus huttoni

A medium-sized brown-and-white shearwater with darker upperparts extending to the head. A dark brown mottled collar extends down from the neck and fades into the white breast and underparts. The underwings have an off-white central patch that merges into the dark borders of the wing with distinctly dusky “armpits.” Breeds solely on the mainland of New Zealand, where nesting is restricted to steep tussock slopes in the alpine zone of the Seaward Kaikoura mountains. Slightly larger and darker than the Fluttering Shearwater, with less white showing on the chin and throat.
