were moving rapidly in a northerly direction. A few were seen sitting on the water, usually in the company of a few storm petrels. Leach's Storm Petrel (Oceanodroma leucorhoa) 114 + 2 nocturnal Storm Petrel sp. (unidentified) 12 + 2 nocturnal Probably all of the storm petrels seen on this survey were Leach's, but as similar types could easily be overlooked, they were recorded on the daily log sheets only as white-rumped storm petrels. The density distribution has changed since last cruise, but this behavior has been noted without explanation since January. The general trend of increase in the north section would seem to be indicative of a migratory movement, but no other data were collected which substantiates this. Direction of travel did not follow any obvious pattern, and the variation of local densities would not seem likely if a loose migration was under way. Red-tailed Tropicbird (Phaethon rubricauda) 2 Both sightings were in the north section; neither bird was attracted to the ship, and in fact both seemed to avoid it. Glaucous-winged Gull (Larus glaucescens) 0 This is the first grid survey to date on which no Glaucous- wings were seen. The pattern of decline has closely followed that of the Herring Gull. Herring Gull (Larus argentatus) 4 All sightings were of adults in the north section. The continuing decline of the grid population suggests that breeders are returning to the nesting islands.
