I took this photo on a trip off the Auckland Islands, New Zealand and only recently took any notice of it. Any ideas?
It looks to me like a Prycroft or Cook's, but the underwing doesn't seem to have enough black on it. It could be a Broad-billed Prion with the underwing, but there looks like too much white on the face.
For an idea of size, this is the full frame of the image and it was shot at 165mm
