Buller's Shearwater

Scientific name:

 Puffinus bulleri

 

 

Conservation status:

 Naturally uncommon

Mainland status:

 The NZ coast, esp. off Northland, the Hauraki Gulf and the Bay of Plenty

Size:

 46cm, 425g

Lifespan:

 Unknown

Breeding:

 November – May

Diet:

 Krill, fish, salps and jellyfish   


The Buller's shearwater is quite strikingly marked. The head and back of the neck are dark brown, the underparts are white and the back and upper wings are grey with a bold dark ‘M’ across the wings, lower back and rump. The long wedge-shaped tail has a broad black tip and the bluish grey bill with a darker tip is long and slender. The legs and feet are pink with dark outer toes and outer edge of the tarsus. They have a braying call.

Their diet is small krill, small fish, salps and jellyfish. The also scavenge for scraps around fishing boats.

They breed in large dense colonies on the Poor Knights Islands. Breeding takes place between November and May after they return in mid-September to court and then clean out their burrows in October. The single white egg is incubated by both sexes for about 51 days and most chicks fledge at about 90 days old.

During April to late May Buller’s Shearwaters migrate to the northern and eastern North Pacific.

Although their breeding sites are well to the north of Tiritiri Matangi, Buller's shearwaters are seen frequently from the boat travelling to and from the Island, and can often be seen around fishing boats from the East Coast track.
