I have about three dozen photos of this pair of birds flying by the ship; I've included four in this post to indicate consistency among photos, as well as both dorsal and ventral views. According to the bird expert on the ship (Ken Wright), they are different species. The trailing bird (on the right) appears to be a Soft-plumaged Petrel, while the leading bird (on the left) appears to be an Atlantic Petrel.

This record is for the trailing bird to the right.
