About the Buller's Shearwater
Buller's shearwater (Ardenna bulleri) is a Pacific species of seabird in the family Procellariidae; it is also known as the grey-backed shearwater or New Zealand shearwater.

Adults birds are 46–47 cm (18–19 in) in length, with a 97–99 cm (38–39 in) wingspan, and have been recorded to weigh 342–425 g (12.1–15.0 oz). The upperside of Buller's shearwater is bluish grey. A blackish stripe runs from the tertiary remiges to the primary wing coverts. The primary remiges are blackish, also; the two black areas do not meet at the hand, however; the area between them is a rather light grey, and under bright light may appear almost white. With the bird facing upwards, the pattern gives the impression of a broken black "M", with light grey interspersing areas.
