breeds on subantarctic island slopes

Size
Length: 25-28 cm, Weight: 120-160 g
Lifespan
15-20 years
Diet
Carnivorous. Feeds on small fish crustaceans and squid. Forages by surface-seizing and shallow diving. Often feeds in association with tuna driving prey upwards.
Habitat
Open ocean and pelagic waters. Breeds on remote subantarctic islands in burrows dug into soft soil under forest canopy or in tussock grasslands.

Main Threats
Introduced predators on breeding islands including rats and mice that eat eggs and chicks. Light pollution disorienting fledglings. Climate change affecting prey availability.

Te Ao Māori
The subantarctic little shearwater has no recognised Māori name. It is a bird of remote subantarctic islands. Shearwaters (tītī) were traditionally harvested by Māori for food and oil. This subantarctic form was known to southern iwi. They visited the islands to harvest chicks. The practice continues today under modern management. The connection is historical. It is also practical. The association remains. The tradition persists. The resource is valued.
A small dark shearwater that lives at the edge of the Southern Ocean. It is a bird of the roaring forties and the furious fifties. The subantarctic little shearwater is a subspecies found only in the subantarctic. It is smaller than the northern form. It is darker. It is also more secretive. The isolation defines it. The environment shapes it. The bird adapts to the extremes. The plumage is dark grey above. It is white below. A dark cap sits on the head. The face is white. It looks like a miniature muttonbird. The resemblance is striking. The identification requires care. It flies low over the water. The wingbeats are rapid and whirring. The motion is distinct. The silhouette is compact. The flight path is direct. Feeding involves small fish and crustaceans. The bird dives from the surface. It flies low. It patters. It dips. It snatches. The technique is efficient. The energy cost is low. The catch is secured. The hunger is satisfied. The process repeats. The survival depends on consistency. The ocean provides. The bird takes. Flight is rapid and erratic. Short glides alternate with sudden banks. A subantarctic little shearwater in a storm is in its element. The wind does not defeat it. The bird uses the turbulence. It rides the gusts. The movement is unpredictable. The control is absolute. The mastery is real. The weather is an ally. Breeding takes place on remote subantarctic islands. The burrow is dug into soft soil on a steep slope. A single white egg is laid. Both parents share incubation duties. The chick is fed on regurgitated fish oil. The nutrition is rich. The growth is steady. The departure is timed. The cycle is complete. The return is annual. In New Zealand these birds breed on the Antipodes the Aucklands and Campbell Island. The populations are modest. The numbers are limited. The distribution is restricted. The location is remote. The access is difficult. The isolation is preferred. The safety is real. Confusion with the common diving petrel is common. The shearwater has a longer bill. The diving petrel has a shorter one. The distinction is morphological. The identification requires attention. The features are specific. The comparison is necessary. The error is frequent. The correction is visual. The main threat is introduced predators. Rats and mice have wiped out populations on some islands. The subantarctic islands are mostly predator-free. The absence of mammals is critical. The protection is real. The security is fragile. The risk remains external. The vigilance is constant. The call is a low moaning chatter. It is heard only at night. On the Antipodes with the wind off the sea and the shearwaters calling the sound is constant. The noise carries. The atmosphere is heavy. The presence is felt. The auditory landscape is defined by this voice. It persists. This is a bird of the wind and the waves. It is an inhabitant of the most remote places on Earth. The distance is significant. The environment is harsh. The adaptation is total. It carries on.
