Glaucous-winged Gull ( Larus glaucescengj 
No. Obs.: 2 
Both of these birds were immatures and were recorded separately in 
Sections R and V. The individual in R followed the ship for about three 
hours, but the one recorded in V followed only a few minutes. Since^ t 
and 13 individuals were recorded in EGS 13 and 20, respectively, it in¬ 
dicates that most of these gulls have now departed. Since no adults o 
this species have ever been recorded in the Grid, it cannot oe said 
that these birds are migrating north for breeding.

Of the 50 individuals (adjusted total) recorded, the birds were classi¬ 
fied by the following age classes: Adults - 27 (54.0 percent), oub- 
adults - 4 (8.0 percent) (with plumage near that of adults, but dark 
mottling occurring around the neck and nape and also dark spots in oau 
feathers for some birds), and Immatures - 19 (38.0 percent). HarQ 7 
any daylight passed without at least one of these birds within sight o 
the ship. The lowest number recorded was in Section R, the larthest 
from land, which is quite the reverse from the last two surveys (EGS 
19 and 20) where this section had the highest totals for each of the 
respective trips. 
Black-legged Kittiwake ( Rissa tridactyla ) No. Obs.: 1 
A single immature bird was seen in Section T on 26 March and fol¬ 
lowed the ship for over an hour. This lone sighting indicates that 
the birds have migrated northward toward breeding grounds and thao only 
stragglers remain in the Grid. 
Aleids 
All nine individuals were recorded on 24 March in Section 3. None 
of the birds were identified to species.
