This suggests that some of the winter breeding population from Guadalupe is presently in the Grid. 3. High numbers of storm petrels were observed moving west in section "T" on 8 November. This population's status is unclear as yet. The favorable observing conditions no doubt contributed to the high counts, but it is clear that there has been a significant increase since the last survey. Birds were attracted to slicks in sections V and Y where peak counts were recorded. On several occasions large (10-plus) flocks were observed over slicks. On two occasions birds were noted feeding on large dead squid in these slicks. A large series of specimens was collected and still awaits complete analysis. Red-tailed Tropicbird # OBS: 5 Red-billed Tropicbird # OBS: 5 Tropicbird sp. # OBS: 2 Both tropicbirds were present on the Grid at similar densities, but the Red-tails were found in the west (sections U & Y) and the Red-bills in the east (sections V & Z). A group of four Red-tails circled the ship calling on the morning of the 4th. The Red-bill sightings were all of single birds. Mallard # OBS: 7 Pintail # OBS: 2 A pair of Drake Pintails and a flock of Mallards constituted the 2 sightings of ducks. "Waterfowl" # OBS: 23 "Waterfowl" here includes Loons, Grebes, Ducks, Geese, & Cormorants. A flock of 22 birds in section "Y" was possibly composed of western Grebes. A waterfowl in "W" was probably an Arctic Loon. Sparrow Hawk Falco sparvarius # OBS: 1 A male was collected off the mast at sunset of the 1st in section R. Golden Plover Pluvialis dominica # OBS: 1 A winter-plumaged bird was collected in section "Y". Red Phalarope # OBS: 166 Northern Phalarope # OBS: 1 Phalarope sp. # OBS: 25 Red Phalaropes have increased in both the grid and nongrid sections. Birds were scattered in eight sections of the Grid, the center-west
