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:
