EASTERN AREA CRUISE NO. 36 (EASTROPAC Monitor Cruise 76) SUMMARY OF EASTERN PACIFIC OCEAN BIRD OBSERVATIONS 19 February - 05 April 1968 aboard the R/V DAVID STARR JORDAN Prepared by Richard S. Crossin

The following report summarizes bird and marine mammal observations conducted aboard the R/V DAVID STARR JORDAN during EASTROPAC Monitor Cruise No. 76 conducted by the Bureau of Commercial Fisheries for the purpose of tuna research. During the period 19 February through 5 April 1968, 269.2 hours of diurnal observations were conducted over a distance of 1996 nau- tical miles and 4,589 sea birds were recorded. Excellent cooperation and assistance were received from both Dr. Thomas (Cruise Leader) and the scientific personnel and from Captain Forster and the ship's personnel. Their time and assistance given to launching and operation of the skiff are directly responsible for the successful bird collecting activities performed during this cruise. The cruise track extended from San Diego along coastal Baja California to Manzanillo, Colima, on the Mexican mainland where the ship refueled, and thence to a point offshore Acapulco, Guerrero, where oceanographic studies were initiated. From Acapulco the cruise extended to 105° longitude and thence southward on this line to 20° S latitude. The original cruise plan, designed for a return north along 98° longitude, was changed and a return north via 112° longitude was made. This latter cruise leg was originally designed for the R/V THOMAS WASHINGTON, but serious illness to a crewman aboard that ship required that a run be made to the Galapagos. The WASH- INGTON presumably conducted survey work along the 98° longitude line after departing the Galapagos. Except for a span between 20° S- 105°W to 10° S- 112° W, oceanographic work was continuous aboard the JORDAN until return to Manzanillo. METHODS Bird observations were primarily conducted only while the ship was underway between stations. Some observation time was spent while in the skiff during station time and these data are included in the total. Ob- servations were made from the flying bridge which afforded the best poss- ible view of the surrounding ocean. As Harrington pointed out in the Oct.- Dec. 1967 cruise report, continuous binocular observation for one person is impossible and birds were primarily spotted with the naked eye, with subsequent glassing for identification aid.

-3- Collecting was performed whenever possible. Use of the small skiff whenever weather conditions permitted was made during several long ocean- ograpic stations. Oil slicks were usually spread during these times in attempts to attract storm petrels as well as other species. Throughout the cruise 149 birds were collected; the majority of these were storm petrels of two species. Preparation of specimens at night occupied so much time that nocturnal observations were not held. Spot checks were made to ensure that species different from those recorded during diurnal observations were not being missed, but these times were not recorded. Because of the time needed to write the present report, only a few hours daily of observation time were conducted during the return coastal run between Manzanillo and San Diego. Considerable observations have been conducted through this area and in fact reliable density estimates cannot be made whenever the ship is close to land. The present cruise has been divided into sections according to the water types listed below. In most cases these water masses do not appear to be distinct boundaries for bird species. However, since we are dealing with pelagic species, subdivision by natural oceanic zones seems more ap- propriate than arbitrarily chosen lines. Delineation of the various cur- currents was made from analyzation of oceanographic data. AREA A. COASTAL WATERS Time span: 20-27 Feb. and 29 March-5 April. All coastal waters to 150 miles from shore from San Diego to Manzanillo and return are included in this area. Several different water types are undoubtedly included here as suggested by the distribution of certain pel- agic bird species, but the usual land based species dominate throughout. Large flocks of mixed Sooty Terns and Townsend's Shearwaters were encoun- tered at the mouth of the Gulf of California. AREA B. NORTH EQUATORIAL CURRENT WATERS Time span: 28 Feb.-1 March and 24-28 March. Boundary limits: 7° N latitude - 13°-30' N latitude. Moderately high numbers of large shearwaters, large Pterodroma, Leach type storm petrels and Sooty Terns were encountered in this area. Some in- fluence of Clipperton Island based species also affects this region. AREA C. NORTH EQUATORIAL COUNTER-CURRENT WATERS Time span: 2-3 March. Boundary limits: 4°N-7°N latitude along 105°longitude and 5°-30' N to 7°N along 112°W longitude.

-4- A moderate number of large Pterodroma and Wedge-tailed Shearwaters were noted as well as fairly high numbers of Leach type storm petrels. The north and south boundary lines of this current are probably richer in ani- mal life available to birds than within the current itself. AREA D. SOUTH EQUATORIAL CURRENT WATERS Time span: 4-10 March and 20-23 March., Boundary limits: 4°N latitude to 11°-40 S latitude along 105°W longitude and 5°-30 N latitude to 2°-30' S latitude along 112°W longitude. Low numbers of all species except storm petrels were encountered through- out. Although Leach's Storm Petrels were abundant in this area as well as farther north, practically all of the Galapagos Storm Petrels were recorded here. AREA E. CENTRAL PACIFIC WATER MASS Time span: 11-19 March., Boundary limits: 11°-40 S to 20° S latitude along 105°W longitude and thence northwest and north along 112°W longitude to 20°-30'S latitmde. This area was characterized, and distinct from South Equatorial Current waters, by a deeper mixed layer, an increase in salinity and approximately a 1° C drop in surface temperature. The vast majority of southern hemisphere petrels were encountered with- in the bounds of this area. Red-tailed Tropicbirds and Fairy Terns also showed a center of abundance here. Sooty Terns and Wedge-tailed Shearwaters were abundant both in this area and along northern coastal waters with rel- atively none throughout the intervening waters. SPECIES ACCOUNTS (Note: only species which warrant pertinent discussion are included below. See Table 3 for total avifauna.) Pale-footed Shearwater (Puffinus carneipes) Sightings were usually of single individuals. One bird was shot down over an oil slick, only to get up again, fly through four more patterns and eventually outrun the skiff. Pink-footed Shearwater (Puffinus creatopus) Six of the nine sightings were recorded in large mixed feeding flocks. on 22 February at the mouth of the Gulf of California.

-5- 72 Wedge-tailed Shearwater (Puffinus pacificus) Two major concentrations were recorded. Predominantly dark phase birds were found in the Central Pacific Water Mass and mainly light phase birds in North Equatorial Current waters. These latter may have been from Clipperton Island where large numbers were recorded at this time last year. Approximately equal numbers of both color phases were recorded on the present cruise. One light phase bird was collected over an oil slick. Sooty Shearwater (Puffinus griseus) Slender-billed Shearwater (Puffinus tenuirostris) 7 The few scattered sightings of these very numerous species indicate that the northward spring migration is not through this area of the Pacific. One Slender-billed Shearwater was collected over an oil slick on 19 March and a Sooty Shearwater came aboard on the night of 26-27^March. Townsend's Shearwater (Puffinus puffinus auricularis) 484 Manx Shearwater (Puffinus puffinus opisthmelas) 181 These two races of the common shearwater are readily distinguishable from each other even at fairly good distance. The Manx is brownish dor- sally with dark flank patches. Townsends is quite black dorsally with prominent white "rump patches" as in the Hawaiian race newelli. A concentration of Manx Shearwaters was noted on 20 February near San Benitos Island and another lesser concentration in a huge mixed feeding flock of Sooty Terns and Townsend's Shearwaters on 22 February at the mouth of the Gulf of California. One specimen of Townsend's Shearwater was collect- ed from this flock. Dark-rumped Petrel (Pterodroma phaeopygia) 3 One specimen was collected at 2°-30'N; 105°W. At this locality the bird could conceivably be from either the Hawaiian area or the Galapagos and racial designation must await comparison of known origin specimens. Juan Fernandez Petrel (Pterodroma externa externa) 35 White-necked Petrel (Pterodroma externa cervicalis) 1 Juan Fernandez Petrels were scattered in low numbers throughout all pelagic areas. Practically every individual was in heavy molt with large white patches in the primary and secondary regions. Two specimens were coll- ect over oil slicks. The one sighting of White-necked Petrel was unmistakable and I am cer-tain that none of these were recorded as Juan Fernandez 'etrels. This in-dividual was in completely new fresh plumage indicating an earlier molt than in the Juan Fernandez Petrels.

-6- Black-winged Petrel 15 (Pterodroma hypoleuca nigripennis) Bonin Island Petrel ? (Pterodroma hypoleuca hypoleuca) 4 White-winged Petrel (Pterodroma leucoptera) 1 These small Pterodroma were almost without exception recorded south of the South Equatorial Current in the Central Pacific Water Mass. This in- dicates their preference of a distinct water type. These forms will al- ways pose identification problems and unless the individuals are close and viewed under good conditions, specific designation is hardly more than a guess. The sightings referred to Bonin Island Petrels ? could well have been the race P.l. brevipes of the White-winged Petrel. At least 13 other sightings were recorded simply as small Pterodroma. Cooks Petrel 1 (Pterodroma cookii) Excellent views of a single individual were made on 1 April at the mouth of the Gulf of California. I am reasonably certain I saw none of these in the concentrations of similar small Pterodroma near 20°S. Harcourt's Storm Petrel (Oceanodroma castro) ? 8 Leach's Storm Petrel (Oceanodroma leucorhoa) 178 Galapagos Storm Petrel (Oceanodroma tethys) 15 unidentified white-rumped storm petrels 213 Except for abundant coastal species, white-rumped storm petrels were second in numbers only to the Sooty Tern. High densities were recorded in both the North and South Equatorial Currents. Numbers dropped off consid- erably south of 5°S latitude. Despite the elaborate "Keys" and other identification aids proposed by Project members, a white-rumped storm petrel at 100 yards is just that! The fantastic amount of variation in rump patches of Leach's easily covers the ranges of this character of all other white-rumped species. In time of molt Leach's tails are not necessarily forked; they occasionally may dabble their feet as do Wilson's; and their flight may be as erratic or as slow as any of the other species, depending upon their mood. I still maintain that the "Crossin Method" * of field identification of this group is the only sure way. By this method 125 specimens of white-rumped storm petrels were taken during the present cruise. Examination of this large series only emphasizes the folly of attempting to apply specific designation to all sighted birds. Of the 125 specimens, 112 were Leach's and 13 were Galapagos Storm Petrels. No Harcourt's Storm Petrels were collected and I am uncertain as to whether this species was even seen although I tentatively identified at least eight sightings as belonging to this species. The great variation in size throughout the Leach sample indicates that at least two, and possibly more than two races are represented. Exceeding- ly small birds were taken which weigh less than many of the tiny Galapagos and exhibit most characters of this latter species (for a classical exam- ple, see specimen Field Series # 105225). Such individuals would be im- possible to distinguish from typical Galapagos in the field. On certain * This method avoids the need of heavy, cumbersome field glasses. A light- weight shotgun and plenty of ammo suffice.

-7- birds, where the "typical" forked tail and "typical" divided rump of Leach's were not evident because of molt or badly shot birds, the color of the oil (uropygial) gland was found to be a reliable character to separate these two species. Leach's have a creamy-white oil gland, that of the Galapagos is a dark grey. Any combination of the two or more races and the two species were encountered together in the field. Most specimens were collected over artificial oil slicks made with Wesson and/or cod liver oil. Throughout these oil slick operations I had the opportunity to test an old suspicion that storm petrels are able to detect an oil slick by smell. The evidence gathered during the present cruise strongly suggests this and a note concerning details of this phen- omon is being prepared for publication. Identification of stomach remains in storm petrels is practically a lost cause because the majority of food is small, soft-bodied and quickly becomes unidentifiable through digestive action. In a few specimens of Leach's, however, the remains of squid were plainly identifiable. One stomach contained the outer coat and "pen" of a squid which was estimated to be ca. six inches long in life. It is doubtful whether storm petrels are large or ferocious enough to catch such a live animal and I presume wounded animals are probably taken over feeding orgies of tuna. One Leach's had copepod remains in the stomach. White-throated Storm Petrel 3 (Nesofregetta albigularis) All three individuals were sighted south of the South Equatorial Current. Black Storm Petrel 11 (Loomelania melania) All sightings were made on 22 and 23 February of ship followers across the mouth of the Gulf of California. Fork-tailed Petrel 1 (Oceanodroma furcata) The single sighting was noted with Black Storm Petrels following in the ship's wake on 22 February at the mouth of the Gulf of California. Red-billed Tropicbird 14 (Phaethon aethereus) This is predominantly a coastal species. All sightings were along the Mexican mainland. One specimen was collected. Red-tailed Tropicbird 21 (Phaethon rubricauda) Scattered sightings were made from near 20°S to 15°N, but all occurred along the western leg of the cruise. Five birds, mostly immatures, were collected. White-tailed Tropicbird 2 (Phaethon lepturus) Two individuals circled the ship near 20°S on 13 February. These probably are from one of the southern islands; Easter or Sala y Gomez.

-8- Blue-footed Booby (Sula nebouxii) 25 This is a coastal species with all sightings along the Mexican mainland. Blue-faced Booby (Sula dactylatra) 3 The few birds sighted in equatorial current waters at remote distances from land could come from any of a number of origins. Brown Booby (Sula leucogaster brewsteri) 1019 Great numbers of this species were recorded along the Mexican mainland north of Manzanillo. On 31 March they were abundantly encountered with Laughing Gulls and lesser numbers of Sooty Terns feeding over small groups of sailfish. The white-headed adult males of this race are distinguishable. Red-footed Booby (Sula sula) 31 Most birds noted were dark plumaged immatures. Sightings ranged out to about 400 miles from the Mexican coast. One immature was collected over an oil slick. Frigatebirds 10 The few coastal sightings were presumed to represent the Magnificent Frigatebird (Fregata magnificens). One immature of as yet undetermined species was collected at 2°-30'N; 105°W on 4 March. The nearest land from this position is roughly 500 miles (Clipperton Island) and about 900 miles to the Galapagos Islands. Red Phalarope (Phalaropus fulicarius) 14 Northern Phalarope (Lobipes lobatus) 81 unidentified phalarope sp. 267 Phalaropes were found in large flocks along the Baja California coast and Mexican mainland and scattered small numbers were encountered throughout the entire cruise as far south as 20°S. I believe that the majority of sightings were of Red Phalaropes. Five specimens of this species were collected. One taken on 20 March was molting into the breeding plumage. Pomarine Jaeger (Stercorarius pomarinus) 37 Parasitic Jaeger (Stercorarius parasiticus) 3 Pomarines were common along the Mexican mainland coast and a few were encountered to 10°S. Most of these were in general areas of Sooty Tern concentrations. Two Parasitic Jaegers were recorded with a small group of Juan Fernandez Petrels at 12°S and another was sighted at 12°N. Gulls (Larus sp.) All gulls were recorded along coastal areas. Western and California Gulls were common along the Baja California coast and Laughing Gulls were most abundant along the Mexican mainland north of Manzanillo. One specimen each of Western and Laughing Gulls were collected.

-9- Sooty Tern 1316 (Sterna fuscata) Concentrations of Sooty Terns were found in two general areas. Along the mouth of the Gulf of California on 22 February large numbers were seen feeding over tuna in mixed flocks of Townsend's and Manx Shearwaters. Other lesser concentrations were recorded over tuna or sailfish north of 10°N. Other concentrations occurred at about 15°S on 12 and 16 March where birds were noted feeding over tuna or schools of flying fish. In the latter in- stance the flying fish were believed to be surfacing in huge numbers because of submerged tuna activity. The two widely scattered concentrations (north and south) probably indicate birds from two different origins. Fairy Tern 14 (Gygis alba) Most birds were recorded as single sightings or pairs and often in accompaniment with Sooty Terns in feeding flocks. All sightings were in the southern hemisphere from about 5°S southward.

-10- MARINE MAMMALS Marine mammals were scarce throughout the cruise. The majority of the few seen were along coastal waters. The only spectacular event was being able to view numbers of Pacific White-sided Dolphins through a sub- surface view plate as they performed aquatic acrobatics riding the bow wave in front of the ship. The few sightings are listed below. TABLE 1'. Marine Mammal Sightings on EASTROPAC 76. Species # Date Lat. Long. Pacific Pilot Whale ?
