The New Zealand storm petrel is a small seabird of the family Oceanitidae endemic to New Zealand. Thought to be extinct since 1850, a series of sightings from 2003 to the present indicated the presence of a previously unknown colony. The population of New Zealand storm petrels has been estimated to be less than 2000.
Region
Northern New Zealand and Hauraki Gulf
Typical Environment
Predominantly pelagic, occurring offshore around northern New Zealand with frequent records from the Hauraki Gulf. It forages over shelf edges, tidal fronts, and areas of upwelling where plankton concentrates. Birds come to land only to breed, nesting in cavities or under tree roots on forested slopes of predator-managed islands. At sea it remains close to the surface, often in loose aggregations with other small seabirds.

Once presumed extinct since the 19th century, the New Zealand storm petrel was dramatically rediscovered at sea in 2003. Breeding was later confirmed on Te Hauturu-o-Toi/Little Barrier Island in the Hauraki Gulf. It is a tiny, delicate seabird that forages over tidal fronts and is identified by its boldly streaked white underparts. Intensive conservation and predator control are aiding its recovery.

Temperament
pelagic and wary
Flight Pattern
short rapid wingbeats with low, fluttering glides; frequent surface pattering
Social Behavior
Breeds colonially, nesting in cavities or under roots on steep, forested island slopes. Pairs are monogamous, laying a single egg and visiting nests mainly at night to avoid predators. At sea, individuals often forage in loose groups over productive fronts.
Migratory Pattern
Resident
Song Description
Usually silent at sea. At colonies gives soft trills, chatters, and purring calls, most frequently at night during breeding.
