Red Phalarope Sightings of one on the north leg and 12 (one collected) on the south track approximate the number seen on the last non-grid cruise. Jaegers Three unidentified Jaegers and one Pomarine Jaeger were seen on the north leg. On the south track two Long-tailed Jaegers and 21 unidentified Jaegers (probably mostly Pomarine) were seen. Most were in areas where the Sooty Shearwater were abundant, but none were seen chasing the shearwaters. Gulls Western Gulls were observed on the north and south tracks, but more commonly on the latter. Some individuals were seen 60 miles off San Clemente Island, but most were closer to shore. Herring Gulls were not noted inside the channel islands on either leg, but may have been present in large groups of unidentified gulls. Outside the islands they were present in low numbers, increasing to seaward. Two specimens were collected on the north leg. California Gulls are the most abundant gulls along this coast. Probably most of the gulls on both tracks were of this species, but as it is all but impossible to make the careful identification of each gull in a large flock, most were unidentified. On the south track California gulls were noted as far as .50 miles off San Clemente Island. One adult Ring-billed Gull was seen in the Santa Barbara Channel. Highest numbers of Bonaparte's Gulls were noted on the north track. All sightings on both tracks (all inside the islands) were of adults in breeding plumage. A single Sabine's Gull was seen on the north track just before entering the grid.
