5 Great Frigatebird Six of this species were seen in the grid area in June, a 15% reduction in numbers from 11 in May. All were seen within 300 miles of land. One of this species, an adult male, was collected. Sooty Tern Numbers of this species decreased 23% from 3117 in May to 2413 in June. The largest concentration of this species was again found within 150 miles of Oahu where large flocks, at least half of which were composed of this species, were encountered. One of this species was collected. It disgorged a fresh, undigested squid from its craw. It was taken at 1700 on 4 July from a feeding flock, indicating a diurnal surface availability of squid in this area. Noddy Tern Twenty-three of this species were seen in June, all just south of Oahu. Fairy Tern Numbers of this species increased 157% from 7 in May to 18 in June. Most of these were seen within feeding flocks of Sooty Terns and Wedgetailed Shearwaters. One was observed diving just under the surface for fish in a manner similar to that which Sooty Terns employ during diurnal feeding. All were observed in the western half of the grid area. Skua One of this species was carefully observed on 19 June at close range.
