King Warren B. 1964 Sooty Shearwaters started to pick up toward evening, six in all seen today. April 15--First two tropicbirds of cruise shortly after dawn. Two Wedgetails today, both light phase. Ten Harcourts, all Type B. Two Newell's, one seen by Warren King at close range, other by David Bratley, his first. Thirty-six Sooty Shearwaters today, all singles headed north to west. Bulwer's Petrels plentiful, nine plus 2(?). They came pretty close to ship; hopefully we can collect some when weather gets better. At 0605 a large bird, size of a booby, large and robust with gull like wing beats interspersed with glide, white underparts and dark brown upper parts, flying in short arcs, cutting above horizon. At 0718 another large bird, all dark, flying at 50 feet with constant wing beats, gull or falcon like. Two White-necked Petrels and three dark rumped petrels today, all clearly observed. Feathers looked normal. No mottling. Only four Sooty Terns. A lone Bonin Island Petrel seen, the first of the trip. Area was rich in bird life but no birds seen feeding. It seemed more like they were coming and going to some area near us, probably to south where better food supply is. Dave still a bit queasy. April 16-- Slow day today. Very little bird activity. Only five Sooty Shearwaters, going north to west. Most birds were flying fast in strong wind and few came near ship. Bulwer's Petrel continues in small but consistent numbers two and one (?).
