Hi All

To my eye the petrel photographed by Jack Shick off LHI looks like a typical
Cook's Petrel you would photograph off Little Barrier Island. The relatively
pale grey head considering the light conditions and extensive black smudge
line under the eye and extensive white supercilium matching in patterning
photographs of Cook's taken in November in Hauraki Gulf extremely closely
and differing from the excellent images of Pycroft's supplied by Ross
Silcocks. The tail structure is identical to photographs I have of Cook's at
Little Barrier. It does not show much of a collaring effect forming a fairly
even sweep of contrast below the eye up to the hind crown although a bit of
notching in the ear coverts is interesting. My vote is for Cook's.
