3 Highlights 1) Overall linear density -- .208 -- easily the lowest yet recorded for one survey. 2) Virtual disappearance of fall migrants, i.e., Arctic Tern, Sooty Shearwater, Leach's Storm Petrel. 3) Early hints of the "winter populations" arriving, i.e., Fulmar, Herring Gull, Red-tailed Tropicbird. 4) Continued occurrence of unusual land and shorebird vagrants, in- cluding eight new Grid species: Arctic Loon, Mallard, Yellowlegs sp., Water Pipit, Barn Swallow, Starling, White-crowned Sparrow, Audubon's Shearwater. A special appendix summarizing the birds recorded for E.G.S. ## 1-15 by the higher taxonomic categories, is included here as Tables 3 and 4. General Again the overall pattern of distribution within the Grid finds the highest density in the northeast and the lowest density in the opposite corner: .102 ' .615 ' .330 .130 ' .101 ' .344 .047 ' .107 ' .131 Birds per linear mile The sectional distribution of number of species shows a similar pattern: 6 ' 7 ' 7 5 ' 4 '13 1 ' 2 ' 3 Number of species observed in each section. Phalaropes and Storm Petrels together account for about 55 percent of the total birds observed. Another 13 percent is added by Jaegers. The remaining one-third presents rather a menagerie of odds and ends, loosely categorized as follows:
