2 Grid General Except for the ship-followers and the storm petrels, few birds were seen. Black-footed Albatross, Herring Gulls and storm petrels comprise 173 of the 206 birds noted for a total of 84.4 percent of all birds re- corded. A breakdown by species group indicates the following: Species No. of sightings % of total Albatrosses 40 19.5 Gulls 52 25.4 Storm Petrels 84 41.0 Shearwaters/Petrels 7 2.9 Fulmars 3 1.4 Phalaropes 9 4.4 Kittiwakes 1 0.5 Jaegers 1 0.5 Alcids 9 4.4 206 100.0 Linear Density of Ship-Followers R = .083 S = .457 T = .296 U = --- V - .272 W = .436 Overall = .286 X = --- Y = --- Z = --- Adjusted = .201+ + Adjusted total is actual number of ship-followers recorded, eliminating the duplicate counts for birds following from one section into the next.
