Also in this video is South American Tern, just before the Sabine's Tern (well is it a Sabine's? ---it does look very long winged at first, but I can't get any conclusive details on the plumage). I think the first cut of Storm-Petrel is possibly a Wilson (a bit heavier in flight) but then the immediate cut is that of White-vented SP. As for Black and Markham's - I think it may be correct. The two birds fly differently....too bad the cuts are so short.
