This is the shearwater most often seen in the Inner Hauraki Gulf. In appearance they are dark above and pale below. The head to below the eye, upperparts and thigh patch are dark greyish brown. The underparts and flank patch are white, the white underwings have brownish borders and the armpits are dusky-grey. A partial collar is faintly mottled and the bill is quite fine. The main call at the colony is a rapid staccato ‘ka-how ka-how ka-how ka-how kehek kehek kehek kehek-errr’.

They feed mainly on small fish and krill.

Fluttering Shearwaters breed only in New Zealand in dense or scattered colonies on many offshore islands from Northland to the Marlborough Sounds. Breeding takes place between September and February after they have returned to court and clean out their burrows. The single white egg hatches in November and the chick fledges in late January or early February.

With the spread of introduced predators these birds survive best on pest-free islands.

In autumn and early winter some birds, especially juveniles, migrate to Australian waters.

Fluttering shearwaters are commonly seen around Tiritiri Matangi and can be heard calling at night, especially from North East Bay. They nest on Wooded Island, and may also nest on Tiritiri itself. Visitors to the Island most often see them from the ferry as they flap and glide above the waves; they congregate in large flocks offshore from Gulf Harbour.
