Preliminary Report - Eastern Grid Survey #20 - 3-12 January 1968 Itinerary: 3 January 1200 Depart San Diego 4 January 1231 Enter Grid at Pt. "Ash" 11 January 1408 Depart Grid at Pt. "Oak" 12? January 1030 Arrive San Diego Personnel: Richard D. Chandler (Biologist in Charge) Robert L. Brownell Brian A. Harrington Jeffrey P. Tordoff Survey Vessel: U.S.S. Marysville EPCER 857 Methods One-man diurnal observations were held from the bow, the 01-level bridge, or the open bridge as conditions dictated. The vessel, in gen- eral, is a satisfactory observation platform, being much the same as the Shearwater in regard to stability and ease of using field glasses. No regular nocturnal watches were held; cursory observations during night BT casts revealed only a single bird sighting. Outboard engine failure thwarted attempts to use the Boston Whaler for collecting. Bird speci- mens were collected from bow shooting. Survey personnel took Bathy- thermograph soundings at 0800, 1200, 1600, 2000, and midnight. Cruise Track Numerous mechanical difficulties plagued the vessel throughout the cruise. Captain Anderson is to be congratulated for his determination to complete the operation. Deviations from the nominal track were made as in the past to allow for better coverage of the area. The average speed of ca. 12 knots was found quite satisfactory for field observa- tion. Equally valid observations could be made with speeds up to 15-16 knots, I believe. Conditions Weather was remarkably favorable throughout the cruise. Moderate winds in the northern section gave way to calmer seas and broken skies in the south. Light rain and drizzle on the last day did not seriously affect observations. Grid General Highlights 1. High numbers of alcids in the northern two-thirds of the Grid. 2. Increased numbers of Black-legged Kittiwakes. 3. Increase of Leach's Storm Petrels in the southern third of the Grid.

Species Accounts - Grid Laysan Albatross Diomedea immutabilis # Obs. = 0 No Laysans were observed during the survey. Black-footed Albatross Diomedea nigripes # Obs. = 8 The extremely low density (lowest of all surveys) is curious but not entirely unexpected. Total numbers reached a peak in early December (see EGS #18), then dropped markedly over the two subsequent surveys (EGS #19 and the present survey). EGS #1 and #2 showed a similar rapid decline from late January to February in 1967. Black-feets were recorded from only three subdivisions, R, X, and Z. I would hazard a guess that this scanty information suggests that birds have shifted to the south. All eight birds were dark-rumped individuals. Fulmar Fulmar glacialis # Obs. = 30 .08 .17 0 .02 0 Birds/linear mile 0 0 .01 Fulmar numbers on the overall Grid do not appear to have dropped significantly as yet, although the density peak has shifted even more to the north (first noted in late December). Ninety-three percent of the birds were seen in the north half with over 50 percent being recorded in section "T." Of the 28 birds with color phase recorded 25 (90 percent) were dark and one each light, intermediate, and "double dark" (see Harrington EGS winter '67 reports). Sooty Shearwater Puffinus griseus # Obs. = 1 After the secondary migration peak noted in late November (see EGS #17) Grid numbers have dropped markedly and regularly. Southward movement evidently had all but ceased by mid-December and the distribution suggests a crowding of birds toward the coast. I suspect a small population of birds winters close to the coast during the northern winter. In addition to the single positive identification in area Z, some of the 10 incompletely identified shearwater/petrels may very well have been this species. Herald/Kermadec Petrel # Obs. = 1 A light-phase bird, probably one or the other of the above-named, was observed in section "R" on 5 January. Fork-tailed Petrel Oceanodroma furcata # Obs. = 38 0 0 35 3 0 0 0 0. 0 # Observed in each section
Page 40
4 Fork-tails first appeared on the Grid in early December. Two birds were observed on each of the two December surveys (EGS #18 and #19). The high count recorded on the present survey was due to a single sighting of a flock of 35 in section "T." Leach Storm Petrel Oceanodroma leucorhoa # Obs. = 187 .05 .03 .01 .37 .28 0 .32 .55 .43 Birds/linear mile by section An evidently rapidly moving population (probably a northern one) passed south through the Grid in late November (see EGS #17). The early December survey found moderate numbers on the Grid, concentrated in the northern and northeastern sections. The early December birds I take to be chiefly migrant stragglers and possibly winter "pseudo-residents" from the northernmost breeding populations. By late December numbers over the entire Grid reached an all-time low. The present survey found the same low densities in the northern sections but densities in the southern third were significantly higher. I suggest that the birds now infil- trating the southern Grid are from post- or currently breeding popula- tions on Guadalupe and/or other sites to the south of the survey area. Red-tailed Tropicbird Phaethon rubricauda # Obs. = 1 An adult was observed in section "U" on the 8th. (The forthcoming Annual Summary will discuss the distribution of the two tropicbirds on the Grid in more detail.) Red Phalarope (and Phalarope sp.) Phalaropus fulicarius # Obs. = 44 .01 .01 .15 .28 .05 0 Birds/linear mile 0 .03 .04 by sections The distribution of phalaropes was again found to correlate better with the presence of slicks or "windrows" rather than any specific geo- graphic region. The three collected birds were all females. (See other reports for a discussion of the sex ratio problem.) Glaucous-winged Gull Larus glaucescens # Obs. = 13 .04 .01 0 .01 0 .02 .02 .05 .01 Birds/linear mile by section All sightings appeared to be first-winter birds; all were following the vessel. Numbers have increased slowly since November. Unlike the

5 Herring Gull distribution which shows a fairly progressive trend to push southward Glaucous-wings show no discernible tendency to favor the northern sections of the Grid. Herring Gull Larus argentatus # Obs. = 258 The most constant and conspicuous element of the Grid fauna was groups of this gull following the ship. .6 .5 .1 .5 .3 .4 "Linear density" .1 .4 .1 by section The northern two-thirds of the Grid has densities approximately double that of the southern third. Sixty-eight percent of the aged birds were adults. This is nearly the same as the previous survey (EGS 19; 63 percent), but both recent surveys have a much higher per- centage of adults than that recorded in late November (EGS # 17; 3 of 18 birds: 17 percent). The age distribution (adults vs. nonadults) is not uniform over the Grid; adults are not as abundant in the southern third. Third Percent adults. North 73 Center 79 South 43 Black-legged Kittiwake Rissa tridactyla # Obs. = 153 .17 .38 .28 .17 .43 .36 0 0 .05 Birds per linear mile Total Grid numbers have increased regularly over the last three surveys: EGS # Total Obs. Late Nov. 17 0 Early Dec. 18 4 Late Dec. 19 80 Early Jan. 20 153 This survey's data suggest that the bulk of the Kittiwakes is pushing southeastward through the Grid concentrated in a fairly well- defined "tongue." At the north end of the Grid the highest density is located in the center third; in the center latitudes the concentration is shifted to the two eastern thirds (V and W) and in the south latitudes the only section with Kittiwakes recorded is the easternmost (Z). Per- haps numbers increase again directly to the east of "Z" but no observa- tions were taken over this region.

1 3 January 1968 On leaving San Diego one single gray whale was noted migrating south. This whale being an early single was probably a pregnant female. Four separate schools of Delphinus delphis were noted during an 11- minute period in the early afternoon. School sizes were 35+/-5, 40+/-10, 50+/-10, and 65+/-10. Three of the four schools were noted to have some in- dividuals with whitish patches on their dorsal fins. In one school 75 percent of the dolphins had white patches in their dorsals. Only black dorsals were noted in one pod. Six single observations were made of California Sea Lions through the remainder of the day. 4 January 1968 Three Delphinus delphis were noted slowly moving to the southeast. All had whitish areas on the dorsal. A group of 12+/-2 Risso Dolphins (Grampus griseus) were noted travel- ing south. All-white dorsal surfaces and dorsal fins were noted for several of these dolphins. This coloration is normal for adults of this species. Also traveling south behind the Grampus were ca. 800+/-100 Right Whale Dolphins (Lissodelphis borealis) divided into 6-8 subgroups. The sub- groups traveled in a line one in back of the other, and each subgroup generally "porpoised" out of the water in unison. Lissodelphis commonly associates with other genera of cetaceans. A pod of 10+/-2 Dall Porpoise were traveling south staying near the surface between breaths. Three probably Dall Porpoise were noted some distance from the ship. A large school 30+/-5 Dall Porpoise were recorded traveling south. Two Dall Porpoise were noted diving and milling about the surface. These porpoises were probably feeding. Fifteen Fur Seals, all single except one pair, were recorded float- ing on their backs with flippers and tails in the air. 5 January 1968 One Fur Seal was recorded. 6 January 1968 Five pods of Dall Porpoise were noted this day. School size ranged from 6+/-2 to 12+/-2 with the other three being 10+/-2/5. A westerly direction was recorded for one pod.

Two separate sightings of Fur Seals were made during the day. Both animals were floating on their backs, flippers and tail in the air. Harrington recorded one California Sea Lion which was swimming and diving. 7 January 1968 One Fur Seal was noted floating on his stomach. 8 January 1968 Dall Porpoise 8+1 diving/feeding were observed and one or two por- poise would come to the surface at a time. They would slowly roll, showing only dorsal fins and dorsal ridge (no flukes). Dorsal fins very black except for white on tip and posterior edge. Animals were pursued for approximately 30 minutes. Seal sp. recorded by Chandler. Two additional Dall porpoise were noted feeding later in the day. 9 January 1968. Two Killer Whales were logged by Harrington - one was seen well, ca. 15 feet in length, with dorsal about 1-1/2 to 2 feet high. 11 January 1968 Dall porpoise 12+2 traveling west were recorded. Identifications based on swimming behavior and black dorsal fins with some white on posterior edge. If these were Dall Porpoise they are the most southern recorded ones. A dolphin was noted jumping clear of the water in the early after- noon. Based on behavior it was a Tursiops nuuanu (truncatus). A Baleen Whale was observed traveling east in the late afternoon. Chandler said he saw the dorsal fin. This was probably a Sei or a Fin Whale. Early in the morning 100+20 Delphinus delphis divided into two sub- groups but each was quite dispersed. All dolphins were traveling to the southwest. All dorsal fins noted (15-20 animals) had white triangular mark. Not the whitish/grayish patch of northern or non-Grid Delphinus. The dolphins were pursued for 10-15 minutes but they did not ride the bow. 12 January 1968 - Non-Grid Delphinus ca. 300 animals were noted in the early morning. Later in the morning some 50-70 Delphinus were noted. Color variation was noted on the dorsal fins, flippers, and snouts. No dolphins with the white triangular mark on their dorsal fins were noted.
