Sooty shearwater

Titi | Puffinus griseus

Has dark chocolate brown plumage with silver under-wing, but looks black from a distance

Often seen flying in large flocks

Feeds on fish and squid, can dive to 68 m for up to 40 seconds

Breeds on islands around New Zealand and its subantarctic islands, islands off Chile and Australia and the Falkland Islands, from November to May

Migrates to Japan, Alaska, and California

NZ Conservation Status Declining

Although sooty shearwaters are usually seen in flocks around New Zealand's coast, they migrate individually. Studies with electronically-tagged birds show that birds from New Zealand can travel up to 900 km per day and cover a massive 64,000 km on an average round trip to Japan, Alaska and California.

This is one of the world's most abundant and widely distributed seabirds. Also called muttonbirds, sooty shearwaters are traditionally harvested by M?ori as chicks from islands around Stewart Island.

Sooty shearwater flight paths

The map below shows actual flight paths of GPS tracked sooty shearwaters throughout stages of their breeding cycle.

Blue flights: during breeding season they collect food in Antartic waters.

Yellow flights: after breeding they migrate north.

Orange flights: sooty's feed off California, Alaska and Japan before heading home to start the breeding cycle again.
