The Subantarctic Little Shearwater is a distinct population, sometimes considered a full species, of small shearwater inhabiting subantarctic waters. It shares typical shearwater characteristics but is adapted to colder, southern ocean environments.

Where to spot

Breeds on subantarctic islands including those off New Zealand (e.g., Antipodes, Snares, Chatham Islands) and possibly others. Disperses widely in the southern oceans.

How to spot

Requires pelagic trips into the subantarctic zone. Look for its small size and classic shearwater flight – low over waves with alternating glides and wingbeats. Differentiation from other small shearwaters often relies on geographical location and subtle bill/plumage differences.

When to spot

Breeding occurs during the austral summer (October to April). Pelagic observations are possible year-round within its subantarctic range, though often challenging due to weather.
