S kua 2 Two birds were recorded on 13 June in the vicinity of French Frigate Shoals. Another bird was seen by Vessel B during duplicate observations in the western leewards. Ruddy Turnstone 15 Eleven birds were recorded off Pearl and Hermes Reef on 28 May, three off the same atoll on 30 May and one off Laysan Island on 12 June. Wandering Tattler 1 One bird was seen off French Frigate Shoals. Arctic Tern 3 Three birds were recorded as this species by observers on Vessel B during duplicate observations. Sooty Tern 1447 This species represented 31.9 percent of the total birds recorded (second only to Wedgetails). Recorded densities were highest in the western leeward islands where there are large breeding colonies. Daily numbers were not as high as might be expected, but probably represent normal pelagic numbers. Had offshore observations (within 2 miles of land) been taken, totals would have been much higher. All birds recorded were adults. Gray-backed Tern 57 Small numbers were recorded in the western leewards, but nearly half of the total were recorded near Niihau on 14 June. Blue-gray Noddy 4 Four birds were recorded near Gardner Pinnacles on 26 May. Brown Noddy 189 The species was recorded daily (generally in feeding flocks) in the western leewards. A large concentration of 107 birds (62 percent of the total) was seen on 14 June near Niihau. Black Noddy 39 Thirty-one of the birds were seen off Pearl and Hermes Reef on 30 May. The remaining birds were seen, a few each day, enroute to Oahu from Laysan Island. White Tern 185 Regular sightings were recorded in the western leewards. On 30 May, between Midway and Pearl and Hermes, 113 birds were recorded. The majority of these were in feeding flocks, but many were single sightings as well.
