Shearwater, and one Pomarine Jaeger were collected in the Grid on the 18th. A serum sample was taken from the Jaeger. No other collections were obtained. Eastern Grid Survey No. 17 Over the 686 miles and 74.3 hours of diurnal observations 793 birds of 20 species were recorded. Twenty-three birds of three species were collected. Twenty-four marine mammal sightings were obtained. Highlights 1. Absence of errant landbirds. 2. High numbers of Sooty Shearwaters moving south. 3. High numbers of Red Phalaropes in the eastern sections of the Grid. 4. Unexpected decrease in Fulmar sightings. The overall pattern of bird distribution within the Grid is again similar to many previous surveys with the high density in the northeast areas and low density in the opposite corner: 1.144 2.320 1.596 .158 .582 3.420 .057 .123 .189 Linear density in each section 3 11 9 6 5 7 2 7 4 # Species per section The three major species - Sooty Shearwater, Leach's Storm Petrel, and Red Phalarope - accounted for over 84 percent of the total observa- tions. Loons, ducks, jaegers, and Herring Gulls each contributed about three percent to the total. The remaining five percent included 11 species present in low numbers. Species Accounts Loon sp. # Obs. = 17 Loons (probably Arctics) were seen singly or in groups of 2 to 4 flying southeast across the northeastern corner of the Grid. One bird followed the ship briefly. Laysan Albatross Diomedea immutabilis # Obs. = 3 Single birds were seen on the 19th, 21st, and 22nd, in the south- west part of the Grid. These are the first sightings since early May. One bird followed the ship for over half an hour.
