Seabirds around fishing vessels

Hutton's shearwater

Puffinus huttoni

Endemic to New Zealand, the Hutton's shearwater only breeds at high altitudes in the Seaward Kaikoura Range. Its total population is estimated to be around 300,000 adults. This species may be misidentified at sea as the fluttering shearwater or possibly the Buller's.
