King Warren B. 1964 39 and if the total area of the grid is 450,000 square miles then there were ~375,000 Sooty Shearwaters in the grid today or 750,000 in a twenty-four hour period, assuming nocturnal activities are roughly similar to their diurnal ones. Thats quite a few birds. Just four loosely packed flocks were noted, almost not flocks at all of seven, eight, eight and twenty. Several were seen circling, but not feeding, in a feeding flock of Sooty Terns. All were heading north or northwest depending on how the ship was turned. None came closer than 200 yards. Silver linings were observed on numerous birds all day, when the light was right. Every bird we saw the wing linings of had silver linings. Two Harcourt's SP both type B. Two light phase Wedgetails. Seven shorebirds, similar to those seen previously, small and light colored. Several Sooty Tern flocks, twenty-five, twenty-five and twelve, one of which had a Frigate over it. April 4--Fairly good activity today, but none of it due to Sooty Shearwaters. Black-footed Albatross were with us at dawn (4), increased to 40 during a hydro station at 1310, one of which had a silver by land on left leg. It was on the verge of being caught in the net when the ship all day, but never more than three at a time, usually two or one. Wedgetails present in small numbers, 25 in all, all day. All were light phase. Sooty Terns were the most numerous, totaling 229 with flocks of 115, 60, 15, 6, 6. In addition, they came by in ones and two's all day. Two of the flocks had four and one Fairy Terns respectively connected with them. A Pomarine Jaeger was seen at 0954, pretty far from land. Alone Red-tailed Tropicbird was seen at 1103.
