5 Glaucous-winged Gull (Larus glaucescens) 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 17 and 13 individuals were recorded in EGS 18 and 20, respectively, it indicates that most of these gulls have now departed. Since no adults of this species have ever been recorded in the Grid, it cannot be said that these birds are migrating north for breeding. Herring Gull (Larus argentatus) No. Obs.: 76 Adjusted: 50 R = 7 (.058) S = 28 (.298) T = 18 (.184) U = --- V = 11 (.120) W = 12 (.218) X = --- Y = --- Z = --- Of the 50 individuals (adjusted total) recorded, the birds were classified by the following age classes: Adults - 27 (54.0 percent), Sub-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 tail feathers for some birds), and Immatures - 19 (38.0 percent). Hardly any daylight passed without at least one of these birds within sight of the ship. The lowest number recorded was in Section R, the farthest 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 followed the ship for over an hour. This lone sighting indicates that the birds have migrated northward toward breeding grounds and that only stragglers remain in the Grid. Alcids All nine individuals were recorded on 24 March in Section S. None of the birds were identified to species.
