AUDUBON SHEARwater Two birds collected at the Galapagos This may be the most abundant bird in the immediate vicinity of the Galapagos Islands. Thousands were seen along with many other birds in a hydrographic front at the northwest end of Isabela. Huge "balls" of bait were present here and the shearwaters were walking on the water, quite like the storm petrels do, and then just walking under water and not coming up for as long as 20 or 30 seconds. This behavior was very common at this hydrographic front. Only one Audubon Shearwater was observed at any distance from the Galapagos Islands. SOOTY SHEARWATER The three birds observed just west of the Galapagos Islands may be the first records of this species within the island waters. Sooty Shearwaters were seen in large numbers all along the southern half of Baja California, Mexico. PHOENIX/TAHITI PETREL These large petrels were present in the northern part of the area and also in the southern part, but are absent from a wide area in the center. These two petrels are extremely difficult to distinguish in the field, and only very close observation could enable one to differentiate between them. None of either species was positively identified. JUAN FERNANDEZ PETREL WHITE-NECKED PETREL P. externa There was a small number of these birds in the North Equatorial Current system, not nearly the number which was in these waters in August and September 1967. One White-necked Petrel was positively identified on 23 February (see drawing on at-sea daily log). All the rest were Juan Fernandez or only identifiable to the species level. STORM PETRELS This confusing group has stirred much discussion during the past and I shall add my bit to the confusion. The characteristics I used in determining species are as follows: First: Galapagos Storm Petrels follow the ship and are readily identified by their large white blaze; second: the dividing line on the rump was used to identify white-rumped Leachs at close range; third: Harcourt Storm Petrel was identified by its all-white rump (i.e., no dividing line), and squared off tail. However, I feel rather doubtful about some of the birds which I recorded as Harcourt Storm Petrel as I have recently seen some of Dick Crossin's specimens from the JORDAN cruise. They were in molt and the usual Leach characteristics were not very evident. During five days of collecting at 98°W on the equator I collected 22 Galapagos Storm Petrels and only seven Leach Storm Petrels.
