The collection of this species constitutes the first grid 
record. The specimen was a subadult with light .fat, and was in in 0 
northwest portion of the grid. 
Sabine’s Gull ( Xema sabini ) 2

this species is most apt to occur between 50 and 150 miles of the 
shoreline.

Red Phalarope ( Phalaropus fulicarius) 927 + 7 nocturnal 
The densities of this species have been high and irregular 
over the last three cruises. During this survey unprecedented 
numbers were recorded, especially in the central portion of the qrid. 
Their distribution seems to be very local, as was well demonstrated 
on 22 April. On this day a 20 mile portion of the cruise track was 
) 
surveyed three times (see report introduction.) During these three 
transects virtually no Red Phalarope were seen. Yet just to the 
west (within 20 miles) hundreds were seen along a 20 mile line.
